DESCRIPTION
Units converts quantities expressed in various standard
scales to their equivalents in other scales. It works
interactively in this fashion:
you have: inch
you want: cm
* 2.54
/ 0.393701
A quantity is specified as a multiplicative combination of
units optionally preceded by a numeric multiplier. Powers
are indicated by suffixed positive integers, division by the
usual sign:
you have: 15 pounds force/in2
you want: atm
* 1.02069
/ .97973
Most familiar units, abbreviations, and metric prefixes
are recognized, together with a generous leavening of
exotica and a few constants of nature including:
pi ratio of circumference to diameter
c speed of light
e charge on an electron
g acceleration of gravity
force same as g
mole Avogadro's number
water pressure head per unit height of water
au astronomical unit
The `pound' is a unit of mass. Compound names are run
together, e.g. `lightyear'. British units that differ from
their US counterparts are prefixed thus: `brgallon'. Cur-
rency is denoted `belgiumfranc', `britainpound', etc.
The complete list of units can be found in /lib/units. A
file argument to units specifies a file to be used instead
of /lib/units.

someone updated /lib/units.
