There is also the conversion I use because I never can remember when and
where to add or subtract 32 degrees without thinking about it.
Both scales coincide at -40 degrees, so simply add 40 degrees to the
temperature to start with, then multiply by 5/9 or 9/5 depending on
whether you are converting to a smaller (F to C) value or a larger (C to
F) value. After doing the multiplication, subtract 40 degrees and you
are done.

For the benefit of those of us who struggle with remembering the two
conversion formula for degrees F to degrees C (or vice versa) here is a neat
little algebra expression I teach:
5F - 9C = 160
Substitute and solve for the remaining unknown.
