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
      units, type:
