That's equivalent to 12½mm on a crop body.
Where are you getting your math?
Brian's right... with a 1.6 crop factor, you have to multiply 20mm by 1.6 which means a 20mm lens on FF is equivalent to 32mm on a crop sensor.

I think there's been some confusion. I think what he meant was, to get the same field of view on a crop body, one would need a 12.5mm lens.Isn't that backwards? A 20mm on a FX is 30mm on a crop body? (assuming a 1.5 crop factor, it could be more or less)
If his camera is FX... 20mm is 20mm, no conversion needed.
