SYNOPSIS
units
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
* 2.54000e+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.

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
