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 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 gen‐
erous 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 not recognized as a unit of mass; lb is. Compound names are
run together, (for example, lightyear). British units that differ from
their U.S. counterparts are prefixed thus: brgallon. For a complete
