Units

Units is a simple unit conversion utility for the iPhone/iPod Touch. Unlike most other unit converters, Units looks and works a lot like a calculator. You punch in digits and Units does the conversion on the fly.

Units remembers the last used conversion units for each mode. Modes that you use often can be saved for quick access via 3 user-assignable buttons.

Currency exchange rates are updated once a day from our server, but you can also do a manual update when you want to.
