units - converts quantities expressed in standard scales to other scales

units

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:
