You mean like "to get the length of your dipole antenna, divide 468 by the frequency"?
(which gives you the length in feet, of course.) One of the reasons I never became a ham, sort-of.)

I like computing with units, except for (theoretically) needing to know the units of assorted universal constants, which sometimes get really ugly...
Not terribly happy that even metric has its variations (cgs vs mks vs si, for instance.) But at least if you get those wrong, you're likely to be off by enough that you'd notice...
