The impressive Calculator in Windows 10 for phones will convert all the things

One of the less glamorous, yet still essential, new apps in the Windows 10 Preview for phones is the Calculator. It's one of those apps we just assume will be there when we need it, but with Windows 10 it's becoming immensely more useful. Gone is the simplistic Calculator of old from Windows Phone 8.1, and in comes a new, feature packed version with scientific calculators and conversions galore.

Read on for a quick look at what it can do for you.

Within the app you've got options for standard, scientific and programmer calculators, each important to someone who'd need such a thing. But now, instead of needing a third party app, you'll have the stock option to take care of you.

There are also a number of categories for converting values. The full list reads as follows:

  • Volume
  • Length
  • Weight
  • Temperature
  • Energy
  • Area
  • Speed
  • Time
  • Power
  • Data
  • Pressure
  • Angle

For example, in temperature, you're given three options to convert between celsius, Fahrenheit and kelvin. Speed lets you go from kph to mph and even knots, mach, feet per second and more besides. There are so many options it's tough to see whether anything may have been left out, but there's every chance it's covered all the bases you'll ever need.

It's also a really nicely designed application. As with other new apps that we've seen there is a 'hamburger' menu on the left, which slides out to give you access to the multitude of options available. It doesn't appear to work in landscape mode right now, though that could still change.

As we said up top, it's not glamorous. But it's incredibly useful, and it's reducing the number of third-party apps you'll need to use at the same time. Check out some screenshots of it all below.

  • So much of ss in one post.
  • That too for a calculator+converter app
  • And if I'd only put in a couple you'd all be screaming for more images. Can't have it both ways!
  • It's literally the same app as on Windows 10 for PC. People can look at it there if they have the preview.
    But whatever, some people have neither :P
  • You know what...I never even noticed that you could change the calculator type on the PC Windows 10 preview. This is pretty sweet. Thanks!
  • :D
  • Keep posting more imgs on posts
  • What about the music app
  • Too much of material design I see
  • Let MS known through the user feedback site
  • I disagree. It look very clean and simple to me. If this is the future of Microsoft design, I'm very excited. I'm looking forward to trying Windows 10 when it is released for more phones.
  • "Too much of material design I see" Metro/Modern UI was a heavy influence on Material Design (iOS 7, for that matter).  Google is just late to the party.  However I think MD is better because you can customize it, unlike Metro.
  • What will they do when Google copied them stop using there own design?
  • A lot of 3rd party apps are gone..!!
  • Too me that's a great thing. Not that I don't want to see 3rd party app developers prosper, but how great is it to have a bunch of stuff you want/need native in your OS. This is why Windows is top on the list for me of OS's
  • There already was a MS converter, so they just put the two together and added some. You can still get a 3rd party converter if that's what you want...
  • Looks great on my 1520...oh, wait
  • Eh, it's still in beta. Complain if the full release doesn't work on your phone.
  • I will have to agree with AXmantim, with my 1520 being my dialy driver with work vpn I will gladly wait or install it on my 920 when it becomes available, maybe even by the 635.
  • Is that lumia 530?
  • *630
  • That's 1520,special edition tp win 10 for phone for windows central
  • Excellent! I always think basic conversions should be baked in to the os!
  • If you start giving a method for all basic operations like add, subtract, multiply, divide in OS APIs then the OS would become bloated!! C#, JavaScript is soooo powerful !! Don't worry
  • Cortana could do all this for you anyways
  • Cortana is available for a fraction of users...
  • - Cortana, what is 16kg in pounds?
    - The internet and I aren't talking right now. - Cortana, what is 63 inches in metres?
    - Starting Angry Birds. It's that good.
  • +920 likes.
  • I use Cortana for conversation and no problems. Rarely get the internet and I aren't talking right now. But, it's great to have both options. Cortana and voice is becoming more and more useful for me, but that's me.
  • Cortana is non-existent for most of the world, so this should never be the answer.
  • The OS itself doesn't really need all this kind of stuff, that's true, but I also think that any OS should come with a default application that can handle it. I think Poirots wanted to say the same - having a default, preinstalled application, not having conversions as a component of the OS itself.
  • Yes, you've articulated it better than I did ;)
  • You are one of the confused congregation, less Features u complain. Now it has more features u whining.    what do you want???
  • Very nice. It seems MS is taking a very comprehensive approach to this update. Touching up and improving from the lowest to highest aspects of the OS. I like it.
  • Exactly
  • They seem to have completely moved away from there carousel layout with the big title to the Hamburger style. While I like it, a lot of people would not be happy.
  • It makes sense though, if you think about it. The carousel/pivot UI of old cannot be replicated in Windows for PC. It would be too awkward to use. Hamburger menus are the way to go if you wanna integrate experiences.
  • I've been hoping for them to utilize mouse gestures for desktops. If you've ever used opera browser 12, there are plenty and they're not awkward at all.
  • Not awkward for you...I've used it as well and the are awkward to me
  • They're awkward for me also. Just put the hamburger menu in the lower right to appease us if they must transition to a new format. The upper left is the worst position possible for one-handed users. I feel like they're sticking a little photo icon of my ex wife on the screen when they copy Android and stick it in the upper left like that. It is that annoying. I left Android for that reason among others.
  • Yes. Please continue to use hamburger, I'm all for continuity but for phones its placement must be at the bottom if its to be useful AT ALL. It simply is bad on a 1520 device and awkward on an 1020 device. Bottom left or right for phones and I'm sold on the new design.
  • I still find carousel/pivot UI is better in ease of use of navigation and usability. Too bad they seem moving away from it. I think its not too late though, some apps in got a tab like navigation at the top and I think they can still implement pivot like navigation, just a different facelift. I also have an iPhone and I hate tapping on tabs instead of swiping between them. I'm glad WP and even Android have carousel navigations.
    Well on tablets and desktops/laptops may not need pivot navigation that much since of wider space, but instead they will be treated as normal tabs similar to Zune. Touch mouse /trackpad can have gestures for this.
  • Agree that top right hand corner is bizarre. I have 930 and have to adjust my phone or use two hands. The ... is so much more convenient and easy to use. Also, swipe gives a beautiful experience that is elegant and unique, so I prefer pivotal menus to clicking on tabs.
  • Keep them features rolling and coming.
  • Just like PC! We're doing great!
  • Very nice and I agree with basic conversions should really be default on a calculator on any OS and I'm glad Microsoft is doing that! I'm really getting swayed in trying Windows Phone haha. Posted via the Windows Central App for Android
  • I wouldn't leave android yet. WP still has a way to go.
  • I agree with buddy, but WP is much more better then Andy...
  • I was a WP user, but I recently switched back to Android. I woudln't say Windows Phone is better than Android yet. It definitely shows more long term promise and is a much more beautiful UI, but it has to mature much more to be on the same level as Android as far as features are concerned. WP10 looks to be a great step in that direction, and if it can attract more app developers and some of the major apps to join the platform, I'll definitely consider it again and jump onboard. I like WP, and despite being an Adroid fan too, I would not mind having a WP10 device in the future as my business phone, and an Android for my personal phone (since it has more apps and integrated services for entertainment/media consumption). Both OS have their merrits and beauty, and I don't think we are served by an either/or mentality. Competition and variety are a great thing. Keep it up Microsoft!
  • .|.
  • I prefer WP over android. Other than a couple of apps I wish I had access too, I find the OS more stable and more secure, which are what is really important to me. The interface is better, to me, and I'm glad I went with WP.
  • with windows 10 it will always be better. as i love the pc features more. mostly all features get common on ask platforms with mobile.
  • Switch...or at least have one of each. Who knows...you might like it. :-)
  • Wow nice
  • W10 looks great. Nice functionality and minimal UI :)
  • I agree, but not everyone. I am actually looking forward to see how the final overall look of the OS :)
  • That Alarm app shows how things are going about UI. And I like it.
  • Can you share screenshots of how looks now the alarm app?
  • Characters look bit tiny, or just me??
  • I for one liked the three dot menu on the bottom better. But I guess it's due to the virtual home etc. buttons. Damn You low end phones with no capacitive buttons.. :(
  • I hate how they're shifting so much of the UI to the top of the screen. It's TERRIBLE for one handed usability, and it's even annoying with two hands on larger phones like the 1520. I'm seriously not going to stop complaining about/deriding this.
  • I'm not either. It seems Microsoft is ready to get rid of the old interface in order to make the same apps on Windows phone and PC. I don't think this is a good way. Neither Google nor Apple have such similar apps however they are popular and successful. Posted via the Windows Phone Central App for Android
  • Agreed! The expanded functionality of the app is superb, but for all that's holy, keep the controls at the bottom!
  • I hate the "suppository" toggle controls.
  • They're basically abandoning their own design guidelines for apps. It reminds me of Android now. But it was easy to see it was gonna go this way. MS used to care about the quality of apps you submitted to the store, now any crap gets put on. They'd rather have quantity than quality.
  • Exactly, and it's not even like Android's way is very good. iOS has arguably more popularity, I don't understand why they don't try to ape its style more.
     
  • I believe Apple has about 18% of the world smartphones market.
  • Very much agreed. That hamburger menu was the horrible ending of a torturous multi year menu transition for Android. It epitomized the worst of the worst in OS decisions for one-handed Android users, and then Microsoft decided to copy it? First there was the convenient hardware menu button at the bottom of Androids, then it was combined with one of the three other buttons. Then manufacturers decided to combine it with whatever hardware button they wanted, then it went to maybe hardware, maybe onscreen buttons with a long press, maybe. After all this annoyance, they ended by putting it in the absolute worst spot possible for one handed, right handed users. After all the pulling our hair out and having our requests ignored for the stupidest OS decision in the history of Android, Microsoft decides to copy it? When the vast majority of their users have small budget phones, are right handed, and use it with one hand? This decision deserves the wrath of users.
  • What do you think of the entire Windows 10 for phone adopting the ellipsis and ribbon interface found in the new Office apps, when compared to whatever is in the preview? I think that consistency from the desktop environment down to phones would be a plus.
  • There are good and useful improvements galore. That isn't bad. Enjoyable free-flowing usability is being replaced with an Android / universal Windows combination that replaces the free flowing swipes and integration with menus and individual apps. It's the different design philosophy that we're opposed to. The "enjoyable to use" design philosophy was squandered because Microsoft took years to add basic features. The design wasn't the problem. The lack of features and apps are what held back the OS.
  • Let MS known through their user feedback site
  • I have done for the Onedrive app. I'm going to refrain from giving feedback on Windows 10 phone stuff until I have it installed though, just so I know for sure whether it's how I perceive it to be.
  • @EssThree. I totally agree with your comment. I find the top right hand corner difficult to reach on my 930, so have to adjust the phone or use two hands. Long love ...
  • I'm glad I'm not the only one that thinks the design of their universal apps is horrible. It looks messy and reminds me of Android. They seem to be abandoning the design principles that make Windows Phone unique and delightful. Aesthetics aside, these apps are also less convenient to navigate around. Pivots and horizontal swiping made things effortless. Now we have to tap on tiny tab buttons like it's 1990 all over again.
  • Even calculator is important for Microsoft, great
  • But not time, ooh no. Waiting for an impressive managament of time too, with alarm, countdown and time laps and all kind of goodies for those.
  • Yes please!
  • The new alarms app in the win10 preview for desktop has all of that.  I believe it is a univeral app that should be coming to phones if it is not already in the 10 preview for phones already.
  • True
  • Good to know, thanks.
  • Yes, the alarm app in Windows 10 for phones does indeed have alarm (which you can now select multiple days with checkmarks), countdown timer, stopwatch with lap and split time, world clock, everything. You can even share your stopwatch.
  • Sweet! Can't wait for my 635 to arrive (on Monday) so I get to try out all them goodies. :)
  • I want to get this OS running really bad. Can't wait.
  • You can't wait, still you have to
  • Point?
  • I know why he said that. It makes sense in Hindi but doesn't make any sense when translated over.
  • If only the world would be rid of inches, feet, miles and Fahrenheit we wouldn't need to do these conversions. Metric FTW.
  • Amen.
  • Lets get rid of all languages as well as English while we are at it. Smdh.
  • Not even close to the same thing! Languages are a subjective matter (and English isn't the most spoken, even if it is the most widely spread), while the metric system is inherently superior to the imperial system in every objective view.
  • Imperial exists because it has a couple of very important and widely used units. One is foot, and the other is Mile. Km can take on Mile, but there is nothing that can replace a foot. Meter is too big and cm is too small.
  • Use decametre.
  • Nothing can relpace foot? Never heard of decimeters? 1ft=3dm=30cm. We can also easily use decimal numbers. 1ft=0,3m. Done. Metric system is on base 10. 1m=10dm=100cm=1000mm. Or, same thing, 1 mm = 0.001 m = 1x10^-3 m. It's way better and helpful in calculations. In the imperial system 1 foot is 12 inches, 3 feet are 1 yard, 1 mile is 1760 yards... there is no base common unit. Another example, you usually say "I'm 5 feet 4 inches tall". You have to use two different units for one number. I say I'm 1,82 meters tall. I can easily use decimals, because 1,82m=182cm. I know immediately that 14,36 km are 14360 meters. 0,543 meters are 543 mm. Can you istantly convert 0,37 feet in inches? Or 1,72 miles in yards? This is why metric system is way better.
  • All praise the Metric Master Race
  • Lol
  • Absolutely agree!  The older I get the more and more I have to use metric anyways, so why not make the change entirely?  Standard is anything but standard and very annoying to use.  About the only things that I have any real concept of in standard are miles and temperature anymore.
  • and maybe you would get rid of half of everything because many things use Inches... for example paper, go and get letter paper on metric system... I would rather put "use inches dear X program" and don't have to deal with "216 × 279" mm that I won't remember.
  • u wot m8   I'd rather buy A4 sheets than whatever inane and random as fuck naming convention the Imperial places use for their paper.
  • Agreed. I live in the U.S. and I agree! I'm a chef and metric is so much easier to scale ingredients in. I write all my recipes in metric...especially baking/pastry ones.
  • Wow
  • The new UI and colors reminds me of Android ICS :/
  • Those colors are just my theme accent.
  • ... so wouldn't you want to use a pretty one to show off the new OS rather than one that looks like a MLP was murdered on your phone's display?  Just a thought.
  • No I like that color. I have it as my chosen background color on Windows 8.1.
  • wow, complainers now tell you how to theme your phone because "It looks like Android" which it isn't... good article and and info for people who can't download the preview yet. These Universal apps will be nice to get once WP and Win10 for my desktop will be released. it would be nice if you could send your information even on calculator, you start on phone and finish on desktop just like music and video should be. in calculator it wouldn't be so useful but on other universal apps and ganes it should.
  • Pay no attention to CaedenV....
  • Telling him what background he should pick for HIS phone!?!? Give me a break....
  • So, Win10 on phones retains it's accent color, while Win10 on tablets won't get one? Basically, that means you would not be able to style both devices the same way. May I kindly ask to add some reviews about WPs greatest deficiency, which is poor backend services and connectivity? How many background processes are allowed? Still only 5?
  • 30
  • If it weren't for the status bar and the keys on the button I would have thought this is Android. I'm very disappointed of the UI changes of Windows 10 :( It is so different from what it used to be. But this are just my 2 cents.
  • I wish this humburger is at the bottom just like the startmenu on PCs for easy access when using one hand on bigger screens Thanks MS for adding this new features, i have been using third part apps, now i can unistall them!
  • I agree with the burger menu at bottom but we should have a choice for right or left handed
  • I hope they put an item in settings to choose which corner the control occupies.
  • Should do the same with the scroll bar. It's completely retarded that it disappears directly after scrolling and is hidden WHILE scrolling if you are right-handed.
  • Of the scroll bar, you have reminded me of how it is difficult to reach the bottom when scrolling a very long list, a very good example for anyone to test :- check on your phone whether Demin update is now avalaible for Lumia 1520 for UK Country Varient, http://www.microsoft.com/en/mobile/support/software-update/wp8-software-...
  • Unless they have mapped the app bar to the hamburger menu, which would include icons as well as text, for existing apps, there will be both worlds which is a rather ugly situation. I am sure I saw a regular app bar in the video review so I believe they are still present too.
  • Would be nice if they could factor in currency conversions somehow, but that might be a bit harder to do.
  • +1. Shouldn't be that hard if they just made it online dependent and Bing fed.
  • If it was within the app I'd disable the background task immediately...don't need my calculator taking up a background task and sucking up some data just to update exchange rates lol
  • Yep. Good project for Cortana integration.
  • Try this: 12345679 x 9 = ?
  • hey can any 1 tell me does win 10 get some new accent colours? really bored of d same colours now!
  • Nope for now, maybe in future builds
  • I wish people could choose exactly the collor thay want 
  • On PC you can choose exactly what color you want. I'm guessing that they are going to bring that feature to Phones eventually.
  • it miss only a currency converter ;)
  • That would be very useful.
  • I thougt of that too!
  • Would require you Calculator app to have a background task. It would use up data and battery updating exchange rates...
  • Why not just do quick online check the monent you do the conversion? No need background task.
  • they forgot the currency converter. :/
  • Hamburger menus. No, thx. I ll stay with 8.1
  • Good.. -_-
  • I love the extra functionality added, seems really nice. However looking at those screenshots, this has Lollipop written all over it... but yeah whatever makes people buy Windows phones :D
  • I don't see lollipop written anywhere on it...there are a lot of other words though...
  • This is what came to my mind. Maybe it's the similar colors, no boundaries surrounding the numbers.. that's what I meant. (not sure why image doesn't appear or maybe it's taking some time to upload, either ways this is its link: https://lh6.ggpht.com/Q7hs8bXlzrLeT5rNVWyKD-nQWHn5lxw8KyIjs1xgfe6cmRLBGN...)
  • This is by far the best calculator app av used on any device...i use my calculator a lot and the basic mathematical solutions works better than on other devices such as percentage calculation on the other hand the asthetic is superb
  • Convertions?
  • Looks good matching the functionality on the Windows 10 for PC calculator... Nice to see a consistency between the two... :-)
  • Cortana solving or teaching math next
  • Wow!
  • It looks like android :(
  • I know Android. And it doesn't look like Android.
