in thread My preferred temperature scale is:

As they drove by me leaving the parking lot they were smiling, and they asked "it's 14C right now, what's that in F?

For me, remembering the approximations 16C=61F and 28C=82F is usually good enough. Then each 1C difference equals nearly 2F. So for the above, I would have said 57F ( 61 - ( (16 - 14)*2) ).
