Convert is a freeware unit conversion application for Windows XP and Vista that allows you to convert many popular units of distance, temperature, volume, time, speed, mass, power, density, pressure, energy and many others, including the ability to create custom conversions.

The full list of unit conversion measurements include:

Force, Light, Mass, Power, Pressure, Speed, Temparature, Time, Volume, Acceleration, Angle, Area, Density, Distance, Flow and Custom Conversions.

To create custom conversions, click on the Custom tab and choose the index number that you want to change. In the first unit box, type in the unit that you want to convert from. In the factor box, type in the value that you multiply the first unit value to get the resulting value. In the second unit box, type in the unit that you want to convert to. When using custom conversions, Convert will allow you to convert to and from the units that you specify so that you do not have to create two separate conversions.

Convert is very easy to use. You simply select the tab of the category you want, enter the input unit, enter the output unit, and type in the input value. Convert shows you the conversion result in the output box in real time as you type.
