You might also consider using an intermediate temperature scale (maybe Kelvin) between your conversions. So to change from scale A to scale B change A to Kelvin then change Kelvin to B. Cuts down on the number of equations required considerably.

I'm developing a program that includes a unit converter which, among
other things, can convert from any one of five temperature scales to
any of the other five temperature scales. The code is hard to
maintain, unfortunately, as I use a rather long conditional (with
multiple sub-conditionals) to determine the "to" and "from" scales.

Is there some (elegant) way to use a matrix-like setup (a
two-dimensional selector or even an array?) that, given two arguments
(a range of five numbers, for each of the temperature scales) will
execute a different one of 25 equations or selectors?
