Unit conversion and calculation.
GNU Units is a unit conversion tool designed to help simplify the process of converting between different systems of units.
The program converts quantities expressed in various systems of measurement to their equivalents in other systems of measurement. Like many similar programs, the units program can handle multiplicative scale changes. It can also handle nonlinear conversions such as Fahrenheit to Celsius, and it can perform conversions to and from sums of units, such as converting between feet plus inches and meters.
Beyond simple unit conversions, units can be used as a general-purpose scientific calculator that keeps track of units in its calculations. You can form arbitrary complex mathematical expressions of dimensions including sums, products, quotients, powers, and even roots of dimensions. Thus you can ensure accuracy and dimensional consistency when working with long expressions that involve many different units that may combine in complex ways.
The units are defined in an extensive, well annotated data file that defines over 2500 units. You can also provide your own file to supplement or replace the standard file.
