NAME
     units - conversion program

SYNOPSIS
     units

DESCRIPTION
     units converts quantities expressed in various standard scales to their
     equivalents in other scales.  It works interactively, prompting you for
     information.

     You specify a  quantity as a multiplicative combination of units
     optionally preceded by a numeric multiplier.  Powers are indicated by
     suffixed positive integers; division is indicated by the usual sign.

     units does only multiplicative scale changes; thus, it can convert Kelvin
     to Rankine, but not Celsius to Fahrenheit.  It recognizes most familiar
     units, abbreviations, and metric prefixes, along with some others that
     include 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

     A pound is a unit of mass.  Compound names are run together (e.g.,
     lightyear).  British units that differ from their U.S. counterparts are
     prefixed with br (e.g., brgallon).  Currency is prefixed with the name of
     the country it comes from (e.g., belgiumfranc, britainpound).

     For a complete list of units, examine the file /usr/lib/units.
