How 'bout this one:

	F = ((C + 40) * 9/5) - 40

The inverse then becomes:

	C = ((F + 40) * 5/9) - 40

You always add 40 to the given temperature, multiply by the appropriate
scaling factor, and subtract 40.  The formula everyone has been giving is
equivalent so it's just a different way to write the equation and, for me,
easier to remember.  Remembering the scale factor (5/9 or 9/5) is a matter
of dimensional analysis and/or remembering 9-degs F to 5-degs C.  Fahrenheit
is a "finer" scale.

	(C+40)*9/5 - 40

	C*9/5 + 40*9/5 - 40
	C*1.8 +  8*9   - 40
	C*1.8 +   72   - 40
	C*1.8 +     32
