Circumference=πxd Multiply the absolute diameter (d) of your round pipe by π (approx. 3.1416). For example, a 10-inch round spiral pipe has a total outer perimeter circumference measurement of exactly 31.42 inches around. Knowing this tells you exactly how far around the pipe wall your custom saddle layout lines need to extend.
