     units - conversion program


     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

                     * 2.54000e+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'.
