UNITS(1) — HP-UX

NAME

units − conversion program

SYNOPSIS

units [- file]

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

∗ 2.540000e+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, and division by the usual sign:

You have: 15 lbs force/in2
You want: atm

∗ 1.020689e+00
/ 9.797299e−01

Units only does 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.

Pound is not recognized as a unit of mass; lb is. Compound names are run together, (e.g., lightyear). British units that differ from their U.S. counterparts are prefixed thus: brgallon. For a complete list of units, type:

cat /usr/lib/unittab

An alternate unit database file can be specified for use with the ‘- file’ option. Units will look in this file rather than the default /usr/lib/unittab for the table of conversions. This must be in the same format as /usr/lib/unittab. This is useful in defining your own units and conversions.

WARNINGS

The monetary exchange rates are out of date.
