NAME
     units - conversion program

SYNOPSIS
     Units  converts  quantities  expressed  in  various standard
     scales to their equivalents in other scales.  It  works  in-
     teractively in this fashion:

          You have: inch
          You want: cm
               * 2.54000e+00
               / 3.93701e-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 pounds force/in2
          You want: atm
               * 1.02069e+00
               / 9.79730e-01

     Units only does multiplicative scale changes.  Thus  it  can
     convert Kelvin to Rankine, but not Centigrade 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 a unit of mass.  Compound names are run together,
     e.g.  `lightyear'.   British units that differ from their US
     counterparts are prefixed thus: `brgallon'.  For a  complete
     list of units, `cat /usr/lib/units'.
