Well, living here on the border I get a mix of C and F and don't need no
stinkin' calculator or complicated formula to do the conversion :>) If
you remember a couple of facts e.g. 18F=10C, and a few data points e.g.
10C, 50F; 40C, 40F etc. then you can quickly come up with a working
conversion within a degree or two. In the example of -30C one uses the
fact that 18F=10C and the point 40C, 40F, and subtract, 40-18=22, viola!
Now if I lived in Timmons I'd probably have remembered the point -30C,
-22F, but around here I tend to use 0C, 32F thru 30C, 86F.
