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 fashion:
You have: inch
You want: cm
* 2.540000e+00
/ 3.937008e-01
A quantity is specified as a multiplicative combination of
units optionally preceded by a numeric multiplier. Powers
are indicated by suffixed positive integers, division by the
usual sign:
You have: 15 lbs force/in2
You want: atm
* 1.020689e+00
/ 9.797299e-01
Units makes only multiplicative scale changes; thus, it can
convert Kelvin to Rankine, but not Celsius to Fahrenheit.
Most familiar units, abbreviations, and metric prefixes are
recognized. So are 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 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, type:
