The purpose of measuring taper angle is to obtain taper angle
This is the formula for calculating a taper: Large diameter of the taper minus the small Diameter of the taper divided by the length of of the taper will give you the taper per inch. You will also need to know the included angle of the taper if you ar cutting this taper. This formula would be Tangent of the included angle divide by 2.
