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

pi

c

speed of light

e

g
