    1 MOA = 1/60 of a degree




    Therefore using trig

    We can calculate the answer using

    X multiplied by Tan (Angle in degrees)

    76 x Tan (32) = 47

    So in our case

    X = 3600 (100) yards and the Angle is 1/60th of 1 degree this will give you the answer in inches.

    3600 x Tan (1/60) = 1.05 inches



    or use this formula in excel

    =(C9*36)*TAN(RADIANS(A11/60))

    Where C9 is Distance in yards and A11 is MOA

    or for the metric

    =(C9*1000)*TAN(RADIANS(A11/60))

    Where C9 is Distance in metres and A11 is MOA answer will be in mm
