GNU 'units' program converts quantities expressed in various scales to their equivalents in other scales. The 'units' program can only handle multiplicative scale changes directly. It uses a functional notation for nonlinear conversions such a Fahrenheit temperature to Celsius temperature.
Andre L. sent in this great write up on the ever useful units command:
Suppose you know that somebody's private rocket got to a maximum height of 328491 feet and you want to know what that means in sane units. Here is a transcript of using units(1), first from the command line and then interactively, to discover this is the same as 100,124.06 meters:$ units '328491ft' 'm' * 100124.06 / 9.9876097e-06 $ units -v '328491 ft' 'm' 328491 ft = 100124.06 m 328491 ft = (1 / 9.9876097e-06) m $ units 2084 units, 71 prefixes, 32 nonlinear units You have: 328491ft You want: m * 100124.06 / 9.9876097e-06
The program can be used almost anytime you need to convert between different units. Here are some more examples:$ units 'tempF(100)' 'tempC' 37.777778 $ units 'furlong' Definition: 40 rod = 201.1684 m $ units 'furlong/fortnight' Definition: 0.00016630986 m / s $ units -v '1 cup sugar' 'grams' 1 cup sugar = 200 grams 1 cup sugar = (1 / 0.005) grams $ units -v 'brgallon' 'usgallon' brgallon = 1.2009499 usgallon brgallon = (1 / 0.83267418) usgallon $ units -v 'usgallon' 'cm^3' usgallon = 3785.4118 cm^3 usgallon = (1 / 0.00026417205) cm^3
