The iPhone may be one powerful (not to mention pretty) piece of equipment, but that doesn't mean we can't use it to do some simple and useful functions. This homebrew allows you to convert measurements from one unit to another.

Who says pretty can't be practical as well? This application lets you convert figures from a variety of different measurements, like temperature and distance, speed and weight.

To install the app, add http://iphone.vladimirkofman.com to your install.app source list and look for the relevant installer. Here's the changelog since the app's first release last December 31:

• 05 Jan: (0.14 release)
1. Fixed Celsius<->Kelvin, kg<->pound conversions
2. Moved Accuracy slider under the actual numbers (I thought it is a better place...)
3. Now when you change a measurement, the application will automatically bring you From and To screens (to save redundant clicks)
4. Added a few units to existing measures, and two new measurements: Power and Torque
• 04 Jan: (0.13 release) Added support for accuracy (precision). Added additional measurement: 'Pressure'.
• 03 Jan: (0.12 release) Added support for storing the last conversion: after application restart you'd automatically get the latest conversion you have previously used. Currently the application remembers the latest Measurement and Units (should it also remember the actual conversion values? As for now it always starts from zero).
• 02 Jan: (0.11 release) Support for negative numbers input (like in temperature), support for epsilon values (the precision is still hardcoded...)
• 31 Dec: (0.10 release) Whew, I've just released the first version of the Converter.
