Bug#123403: ITP: libconvert-units-perl - Perl module for performing unit conversions
What does this do that 'units' doesn't do?
USING `UNITS' NON-INTERACTIVELY
The `units' program can perform units conversions non-
interactively from the command line. To do this, type the
command, type the original units expression, and type the
new units you want. You will probably need to protect the
units expressions from interpretation by the shell using
single quote characters.
If you type
units '2 liters' 'quarts'
then `units' will print
and then exit. The output tells you that 2 liters is
about 2.1 quarts, or alternatively that a quart is about
0.47 times 2 liters.
If the conversion is successful, then `units' will return
success (0) to the calling environment. If `units' is
given non-conformable units to convert, it will print a
message giving the reduced form of each unit and it will
return failure (nonzero) to the calling environment.
When `units' is invoked with only one argument, it will
print out the definition of the specified unit. It will
return failure if the unit is not defined and success if
the unit is defined.
