Dear admin,
what formula do you use for length to angle conversion?

In the attached file you will see a difference between drop (in moa) in a distance of 500m with your formula and the cosines law ...

Thank you,
Bill

cos theta = x/sqrt(x^2+d^2) [rad], where x is the horizontal distance and d the drop.

Can you explain your formula?
