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 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 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
