Example 2: I have a 51T #41 sprocket. 51 / 3.14 * 0.5 = 8.12 inches Click to expand... Geez Aleman, very good! You should be a math teacher.

My figures aint perfect, the actual diameter is a little more than that. Those figures are the diameter at the center of where the chain's link pin will be. The formula works to figure a rough diameter tho.
