No prompting will occur. The units program will print out -only the result of this single conversion. - -.SH DESCRIPTION -The units program converts quantities expression in various scales to -their equivalents in other scales. The units program can only -handle multiplicative scale changes. It cannot convert Centigrade -to Fahrenheit, for example. It works interactively by prompting -the user for input: -.nf - - You have: meters - You want: feet - * 3.2808399 - / 0.3048 - - You have: cm^3 - You want: gallons - * 0.00026417205 - / 3785.4118 - -.fi -Powers of units can be specified using the '^' character as shown in -the example, or by simple concatenation: 'cm3' is equivalent to 'cm^3'. -Multiplication of units can be specified by using spaces, a dash or -an asterisk. Division of units is indicated by the slash ('/'). -Note that multiplication has a higher precedence than division, -so 'm/s/s' is the same as 'm/s^2' or 'm/s s'. -If the user enters incompatible unit types, the units program will -print a message indicating that the units are not conformable and -it will display the reduced form for each unit: -.nf - - You have: ergs/hour - You want: fathoms kg^2 / day - conformability error - 2.7777778e-11 kg m^2 / sec^3 - 2.1166667e-05 kg^2 m / sec - -.fi -.LP -The conversion information is read from a units data file. The default -file includes definitions for most familiar units, abbreviations and -metric prefixes. Some constants of nature included are: -.in +4m -.ta -.ta 9m + -.nf - -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 per unit height of water -mercury pressure per unit height of mercury -au astronomical unit - -.fi -.in -4m -\'Pound' is a unit of mass. Compound names are run together -so 'poundforce' is a unit of force. British units that differ from their -US counterparts are prefixed with 'br', and currency is prefixed with -its country name: 'belgiumfranc', 'britainpound'. When searching for -a unit, if the specified string does not appear exactly as a unit -name, then the units program will try to remove a trailing 's' or -a trailing 'es' and check again for a match. -.LP -All of these definitions can be read in the standard units file, or you -can supply your own file. A unit is specified on a single line by -giving its name and an equivalence. One should be careful to define -new units in terms of old ones so that a reduction leads to the -primitive units which are marked with '!' characters. -The units program will not detect infinite loops that could be caused -by careless unit definitions. -.LP -Prefixes are defined in the same was as standard units, but with -a trailing dash at the end of the prefix name. -.SH BUGS -.LP -The effect of including a '/' in a prefix is surprising. -.LP -Exponents entered by the user can be only one digit. -You can work around this by multiplying several terms. -.LP -The user must use | to indicate division of numbers and / to -indicate division of symbols. This distinction should not -be necessary. -.LP -The program contains various arbitrary limits on the length -of the units converted and on the length of the data file. -.LP -The program should use a hash table to store units so that -it doesn't take so long to load the units list and check -for duplication. -.SH FILES -/usr/share/misc/units.lib - the standard units library -.SH AUTHOR -Adrian Mariano (adrian@cam.cornell.edu or mariano@geom.umn.edu) diff --git a/usr.bin/units/units.c b/usr.bin/units/units.c deleted file mode 100644 index 83e5b4223b229..0000000000000 --- a/usr.bin/units/units.c +++ /dev/null @@ -1,706 +0,0 @@ -/* $Id: units.c,v 1.6 1996/04/06 06:01:03 thorpej Exp $ */ - -/* - * units.c Copyright (c) 1993 by Adrian Mariano (adrian@cam.cornell.edu) - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions - * are met: - * 1.
