The Units program converts quantities expressed in various scales to
to their equivalents in other scales. The units program can handle
multiplicative scale changes as well as nonlinear conversions such as
Fahrenheit to Celsius or wire gauge. Units comes with an annotated,
extendable database defining over three and a half thousand units using
ten systems of units including SI, 170 currencies, plus bitcoin and
precious metals prices, which may be updated daily using the units_cur
script.
