units

Description

The units command 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 is shown 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 Centigrade to Fahrenheit. Most familiar units, abbreviations, and metric prefixes are recognized, as well as the following:


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 US counterparts are prefixed with ``br''. For a complete list of units, enter:
