Convert between units using your own handwriting.
Using the Unit2Unit application, you can quickly and easily convert between many different units of measurement using your own handwriting. For example, you can write “6 ft → cm” and have the pen tell you that 6 feet is equal to 182.88 cm. Abbreviations are the quickest way to perform a conversion, however the tool also allows words. For example, the same conversion can be written as “6 feet → cm”. In addition, tapping on a previously written expression will show the previous conversion result.

The application currently understands a total of 111 units in the following 13 categories: Angle, Area, Computer, Energy, Force, Length, Power, Pressure, Speed, Temperature, Time, Volume, and Weight. Included is a unit reference feature that allows you to look up the appropriate abbreviation for each unit while writing your conversion.
