A lot of the time, 3 is a good-enough approximation of π (it's less
than 5% off). Yesterday I needed to know if the globe on a light
fixture was 5", 6", or 7" diameter.  Measure the circumference with a
tape, divide by 3, and Bob's your uncle.  Of course if you have to do
that very often, you just by a diameter tape. :)
