Okay, thanks. I'm just a part-time math guru.
FYI, I've found a formula to convert focal length to FOV. The formula that it implements is FOV = 2 arctan (x / (2 f)), where x is the diagonal dimension of the sensor. The FOV is measured across the sensor's diagonal, and is therefore smaller across the horizonal dimension, and even smaller across the vertical dimension.

It's not that hard. Just remember 46 is normal. Anything below is WA and anything above is tele.
