Actually, a properly performed "engineering approximation" is done 
entirely in one's head, preferably without resorting to calculation at 
all.

The "back of the envelope" ploy is reserved for cases where one is 
trying to impress a waitress (which effort is inevitably doomed to fail 
of course), or to make it easier to submit the dinner receipt as a 
business expense...
