The Versatile Unit
Converter

The Versatile Unit Converter... The conventional unit converters provide a limited set of conversions, such as length, time, energy, etc. But what if you need to convert the consumption of your car from liters per 100 kilometers into gallons per mile? What if you would like to transform a wavelength into a frequency?

The Versatile Unit Converter manipulates units symbolically, and lets you enter whichever unit you need in the form of a mathematical formula. Other facilities, such as automatic conversion to systems of units (MKSA, CGS, atomic units, …) as well as special conversions (temperature/energy, mass/energy …) are also possible.
