Calculating Foot Candles

Is it possible to calculate or display foot candles on a surface so that we can coordinate rendered lighting conditions with actual photometric calculations?

I believe that the lighting units are in lumens so you would have to calculate based on your surface area the lumen value per foot.
For using emissive materials as static lights—since that doesn’t have a lighting unit there’s no way to calculate the lumen value.

IES lights?
