If you’ll forgive me, one of 8 nerd worldwide who’s lousy at math, asking a dumb question…what’s the mathematical formula for determining the “scale” of a drawing or photo?
Say, I have a drawing of an aircraft. I know the aircraft to be 250 ft. long in real life, and the drawing of it is 3" long. If the drawing is, say, half an inch wide, how do I figure out how wide the actual aircraft is?
Well, thanks for your time,
