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
including:
pi ratio of circumference to diameter
c speed of light
e charge on an electron
g acceleration of gravity
force same as g,

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:
/usr/share/lib/unittab
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.
