NAME
     units - conversion program

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
