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
