Small difference in moa calc

(1/1)

**gvp**:

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

**admin**:

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

Can you explain your formula?

my mistake ... sorry ...
