UNITS(1)                    General Commands Manual                   UNITS(1)



NAME
       units - conversion program

SYNOPSIS
       units [ -v ] [ file ]

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
                  * 2.54
                  / 0.393701

       A quantity is specified as a multiplicative combination  of  units  and
       floating point numbers.  Operators have the following precedence:

              + -            add and subtract
              * / à ÷       multiply and divide
              catenation     multiply
              ² ³ ^        exponentiation
              |              divide
              ( ... )        grouping

       Most familiar units, abbreviations, and metric prefixes are recognized,
       together with a generous leavening of exotica and a  few  constants  of
       nature including:

              pi,Ï    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

       The  is a unit of mass.  Compound names are run together, e.g.  British
       units that differ from their US counterparts are  prefixed  thus:  Cur‐
       rency is denoted etc.

       The complete list of units can be found in /lib/units.  A file argument
       to units specifies a file to be used instead  of  /lib/units.   The  -v
       flag causes units to print its entire database.

EXAMPLE
       you have: 15 pounds force/in²
       you want: atm
           * 1.02069
           / .97973

BUGS
       Since  units  does  only  multiplicative  scale changes, it can convert
       Kelvin to Rankine but not Centigrade to Fahrenheit.
       Currency conversions are only as accurate as the last time someone  up‐
       dated /lib/units.
