Add this app to your lists
All the units you need to convert, wrapped in the best user interface: as easy and intuitive to use as a calculator. It's unit conversion done right!

• Converts as you type (no "Convert" button to press)
• Use mixed units, like feet+inches
• Freely mix fractions (like ½) with decimals (like 0.5)
• Switch units by swipe, long-press, or menu
• Unit calculator with clipboard "memory"
• Supports tablets
• Five UI theme options: Material Light/Dark, Holo Light/Dark, and Classic Gray
• Includes Chinese and Hong Kong units
• Unit categories cover everything from the basics of length, weight and volume to more specialist measurements like magnetic flux density, torque, or radioactive decay. For a full list, please see the Convertor website,
• Currency conversions - converts the major world currencies listed by the Canadian and European Central Banks, complete lists at and - but please note that additional currencies can't just be added at will. The currency rates in the app have to come from somewhere, and if these banks don't list your favored currency, then the app can't show an exchange rate for it.

    Title says it all. Also appreciate how the developer continues to update and enhance the app years after its been released. These are the developers who deserve our highest support.

    My only suggestion would be to have more themes or a cleaner user face (does not have to be 'flat' like everyone else!)
