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

	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
