## NAME

units - converts quantities expressed in standard scales to other scales

## 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**

* 2.540000e+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, 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, (for example,**lightyear**). British units that differ from their

U.S. counterparts are prefixed thus:**brgallon**. For a complete list of

units, type:

**cat /usr/share/lib/unittab**
