       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  op‐
       tionally  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 includ‐

            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'.   Currency  is   denoted   `belgiumfranc',
       `britainpound', ...
