Math::Units - Unit conversion
use Math::Units qw(convert);
my $out_value = convert($in_value, 'in unit', 'out unit');
The Math::Units module converts a numeric value in one unit of measurement
to some other unit. The units must be compatible, i.e. length can not be
converted to volume. If a conversion can not be made an exception is thrown.
A combination chaining and reduction algorithm is used to perform the most
direct unit conversion possible. Units may be written in several different
styles. An abbreviation table is used to convert from common long-form unit
names to the (more or less) standard abbreviations that the units module uses
internally. All multiplicative unit conversions are cached so that future
conversions can be performed very quickly.
Too many units, prefixes and abbreviations are supported to list here. See
the source code for a complete listing.
print ``5 mm == '', convert(5, 'mm', 'in'), `` inches\n'';
print ``72 degrees Farenheit == '', convert(72, 'F', 'C'), `` degrees Celsius\n'';
print ``1 gallon == '', convert(1, 'gallon', 'cm^3'), `` cubic centimeters\n'';
print ``4500 rpm == '', convert(4500, 'rpm', 'Hz'), `` Hertz\n'';
