NAME
       units - convert quantity from one standard scale to another

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 makes only multiplicative scale changes; thus, it can convert
       Kelvin to Rankine, but not Celsius to Fahrenheit.  Most familiar
       units, abbreviations, and metric prefixes are recognized.  So are 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, (e.g., lightyear).  British units that differ from
       their U.S. counterparts are prefixed thus: brgallon.  For a complete
       list of units, type:
