units
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, (for example, lightyear). British units that differ from their U.S. counterparts are prefixed thus: brgallon. For a complete list of units, type:
