          units [ file ]

          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
                   * 2.54
                   / 0.393701

          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
                   * 1.02069
                   / .97973
               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

          The `pound' is a unit of mass.  Compound names are run
          together, e.g.  `lightyear'.  British units that differ from
          their US counterparts are prefixed thus: `brgallon'.  Cur-
          rency is denoted `belgiumfranc', `britainpound', etc.

          The complete list of units can be found in /lib/units.  A
          file argument to units specifies a file to be used instead
          of /lib/units.

          Since units does only multiplicative scale changes, it can
          convert Kelvin to Rankine but not Centigrade to Fahrenheit.
          Currency conversions are only as accurate as the last time
          someone updated /lib/units.
