Formulas for measuring pipe fittings
The formula for a 45 is 1.41. If you measure center of pipe to center of pipe (future) what is the measurement? An example would be if the piping were 12" apart (center to center) you would multiply 12" x 1.41 = 16.92" center to center. Now subtract your fitting allowance (this is the distance between the end of the pipe made up in its socket and the actual centerline of the fitting) say for example (it depends on the size of the fitting) the makeup in the fitting was 5/8" and whats left to center is say 1", you would subtract 2" from your 16.92" measurement or 14.92".
