How can I calculate wind speed based on the rotations of a propeller?

Assume the propeller is always directly facing the wind. If I wanted to calculate the wind speed based on the number of rotations of a propeller, is there an equation for that?

At first I was thinking of off-the-shelf propellers, but then realized probably a home made propeller with a defined pitch throughout the entirety of each blade would be the easiest to do calculations?

I'm not sure if there would be simple vector math, for instance, if the blade pitch is 45 degrees. Or maybe there is some way just to use the circumference and length of the propeller along with the number of rotations per time?
