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
        * / × ÷	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:

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

The complete list of units can be found in /usr/local/plan9/lib/units. A file argument to units specifies a file to be used instead of /usr/local/plan9/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 updated the database.
