NAME
units - conversion program SYNOPSIS
units DESCRIPTION
Units converts quantities expressed in various standard scales to their equivalents in other scales. It works interactively in this fash- ion: 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 suf- fixed 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'. Currency is denoted `belgiumfranc', `britainpound', ... For a complete list of units, `cat /usr/share/misc/units'. FILES

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 fash- ion: 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 * / x -:- 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,n 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

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 /lib/units. UNITS(1)
