.AT 3 units - conversion program 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

" * 2.54000e+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"

Units only does multiplicative scale changes. Thus it can convert Kelvin to Rankine, but not Centigrade 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
