The best unit converter is now even better! Precise, powerful & customisable.
Unity is a unit converter that is like no other - because it's built with simplicity in mind. Unity is also powerful - with over 600 conversion types to choose from already, and more arriving with every update.
Unity can reliably convert units in 18 categories including Angles, Area, Capacitance, Clothing, Currency/Crypto, Data, Data Rates, Distance, Energy, Mileage, Power, Pressure, Speed, Temperature, Time, Typography, Volume and Weight.
You can also save your regular conversions as favourites by tapping the icon on the conversion view and then see them right on the home screen for easy access. Well, there's more important things to do with your day than search for pennyweights and millifarads.
Currency rates are updated every 60 seconds on our reliable servers. Rates are downloaded on startup and can be refreshed at any time from the conversion view. It also has up to date currency graphs to show how rates have changed over the past week, month three months or year.
Using your location, Unity also creates a local currency conversion to your home currency which is easily accessible from the home screen. Or build your own conversion that includes all the currencies for the countries you're visiting on your next trip!
You can set the number of decimal points you would like conversions to be calculated too, work in negative numbers and use the built in calculator for more complex conversions for the highest precision.
As well as the huge range of units already built in, we are happy to add any unit to the app to keep our loyal users happy - just get in touch!

Hi Jamie, the app was much simple before now it’s not usable and is crashing please can you take a look at it
The best converter ever
There can't be a better converter than this! I'm a person who converts units day in and out because of my studies. I have used at least dozen unit converters but wasn't happy with their boring and confusing functionality. Plus it takes so much time to learn how to use. After installed Unity: The Best Unit Converter I have stopped looking for other similar apps. It's just the best. Just like the app their support team is fantastic too. They are always available to help you. I seriously recommend this app to everyone out there looking for a converter powerful.
Developer Response ,
Hi Youssef, Thanks again for your kind words about Unity. We’re so glad you love it as much as we do! 😁
Great app with many useful conversations. As a student living abroad, I've relied on Google to do it for me but this app let's me do it whenever, after syncing currencies and other data.
Clean interface. Looks good. Has what I would need.
Doesn't update it in real time as you type in the number, only a small inconvenience, but still.
Most importantly, I think it needs an inverter button, to switch the units inversely (GBP to USD instead of USD to GBP). Helps when you put items in the wrong box, or when you are converting a lot of numbers between the two units.
