 NAME    [Toc]    [Back]
      units - conversion program

 SYNOPSIS    [Toc]    [Back]
      units [- file]

 DESCRIPTION    [Toc]    [Back]
      units converts quantities expressed in various standard scales to
      their equivalents in other scales.  It works interactively as follows:

           System Prompt       User Response

           You have:           inch
           You want:           cm

      The system responds with two factors; one used if multiplying
      (preceded by *), the other if dividing (preceded by /):

           * 2.540000e+00
           / 3.937008e-01

      After providing the conversion factors, units prompts for the next set
      of values.  To terminate units, press the interrupt character as
      defined for your login.

      A quantity is specified as a multiplicative combination of units
      optionally preceded by a numeric multiplier.  Powers are indicated by
      suffixed positive integers, and division by the usual sign:

           System Prompt       User Response

           You have:           15 lbs force/in2
           You want:           atm

      The system responds with:

           * 1.020689e+00
           / 9.797299e-01

      units only does multiplicative scale changes; thus it can convert
      Kelvin to Rankine, but not Celsius to Fahrenheit.  Most familiar
      units, abbreviations, and metric prefixes are recognized, together
      with a generous leavening of exotica and a few constants of nature
           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.

      Units must be provided in lowercase only.  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, examine
      the file:


      An alternate unit database file can be specified for use with the -
       file option.  units looks in this file rather than the default
      /usr/share/lib/unittab for the table of conversions.  This must be in
      the same format as /usr/share/lib/unittab.  This is useful in defining
      your own units and conversions.

 WARNINGS    [Toc]    [Back]
      The monetary exchange rates are out of date.
