units

units gives conversion rates from one scale to another.

$ units [-f unitsfile] [-q] [-v] [from-unit to-unit]...

The command above will list the value you will need to multiply (*) or divide (/) your original number by to convert to your desired units listed.

The units are defined in an external data file. You can use the extensive data file that comes with this program, or you can provide your own data file to suit your needs. You can use the program interactively with prompts, or you can use it from the command line.

$ units

with no command line arguments, input will be read from standard input.

Generally, use:

$ units [from-unit] [to-unit]...

Useful Options

Below are some important options for units.

$ units --help

will display a help file and exit.

$ units --versions

will display version information and exit.

$ units -f filename
$ units --file filename

Use filename as the units data file rather than the default units data file units.dat.

$ units --check-verbose

Like the -check option, this option prints a list of units that cannot be reduced. But to help find unit definitions that cause endless loops, it lists the units as they are checked. If units hangs, then the last unit to be printed has a bad definition.
