NAME
units - conversion program
SYNOPSIS
*Units* converts quantities expressed in various standard
scales to their equivalents in other scales. It works in-
teractively in this fashion:
*You have:* inch
*You want:* cm
** 2.54000e+00*
*/ 3.93701e-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:
*You have:* 15 pounds force/in2
*You want:* atm
** 1.02069e+00*
*/ 9.79730e-01*
*Units* only does multiplicative scale changes. Thus it can
convert Kelvin to Rankine, but not Centigrade 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
`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'. For a complete
list of units, `cat /usr/lib/units'.
