    They are steel rods with one end having a slightly larger diameter than the other. Standard inch-sized tapered pins have a taper on diameter of 1:48[1] while metric ones have a taper of 1:50.

    the 1:50 is ratio of the whole pin. so ratio 0,5:50 is ratio of one side.
    taper is in degrees -> taper = arctg(0,5/50) = 0,57294

    Inch taper pins are usually 1:48
    Metric taper pins are usually 1:50
    So d = D - L/48 inch sizes
    d = D - L/50 metric sizes
    L is length of pin
