NAME
units - Runs a unit conversion program
SYNOPSIS
units
DESCRIPTION
The units command converts quantities expressed in various standard scales
to their equivalents in other scales. The units command does only
multiplicative scale changes; thus it can convert Kelvin to Rankine, but
not Celsius to Fahrenheit. 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 not recognized as a unit of mass whereas lb is. Compound
names are run together, for example, lightyear. British units that differ
from their U.S. counterparts are prefixed thus: brgallon. For a complete
list of units, enter:
cat /usr/lib/unittab
EXAMPLES
The units command works interactively in this fashion:
$ units
You have: inch
You want: cm
* 2.540000e+00
/ 3.937008e-01

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:
$ units
You have: 15 lbs force/in2
You want: atm
* 1.020689e+00
