And the formula for F -> C
(F - 32) * 5/9 = C

I just remember that 28C == 82F, and that 16C == 61F, so I just pick the one closest to the current temperature (its never far from either here in So.Cal.), and add or subtract the difference ( 1C == 9/5F (or ~2F)).

Update:Of course, I know that 0C == 32F, but its not something I usually have to think about, unless I leave the freezer door open :-)
(16C is considered cold here)...

    A friend taught me this rhyme that helps me out a lot in estimating Centigrade temperature:

    30 is hot,
    20 is nice,
    10 is cold,
    and zero is ice.

    My memory rule is that -40F == -40C and that 0C == 32F. And I learned that from a Donald Duck Comic.
