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:
