How do you measure conduit bends?
How do you measure conduit bends?
Answer: There is no real formula, but it can be calculated with a fair degree of precision. Multiply the radius of the bend you want to make by 6.28, then by degrees, bend and divide by 360. Divide once more by two, measure from the center of the pipe that far then set that mark at the front edge of the bending shoe.

What is conduit bending?
Conduit Bending. Conduit bending is one of the first skills learned by new apprentices in a commercial or industrial shop. They learn to use multipliers for 15°, 30° and 45° for offset bends. Most settle in on the 30° bend since the multiplier is 2. It makes the math very easy.
What is conduit Bender?
