units - conversion program
SYNOPSIS
units
DESCRIPTION
_U_n_i_t_s converts quantities expressed in various standard scales to their equivalents in other scales. It works interactively in this fashion:
_Y_o_u _h_a_v_e: inch _Y_o_u _w_a_n_t: cm * _2._5_4_0_0_0_e+_0_0 / _3._9_3_7_0_1_e-_0_1
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:
_Y_o_u _h_a_v_e: 15 pounds force/in2 _Y_o_u _w_a_n_t: atm * _1._0_2_0_6_9_e+_0_0 / _9._7_9_7_3_0_e-_0_1
_U_n_i_t_s only does multiplicative scale changes. Thus it can convert Kelvin to Rankine, but not Centigrade 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 a unit of mass. Compound names are run together, e.g. `lightyear'. British units that differ from their US counterparts are prefixed thus: `brgallon'. Currency is denoted `belgiumfranc', `britainpound', ...
