Nice hack. Just note that for the case of "no unit" - i.e. for an
empty string - index() returns 1, thus scale becomes 1000 and not
1 (as returned for other characters than the defined ones).
One problem with such arithmetic hacks is that it doesn't "scale"
nicely, e.g. when multi-character unit strings are involved, or
if the scales are not defined in regular forms. - Explicit 'if'
cascades, or string-keys in associative arrays are more robust.
