I am searching for the mathematical relationship between candlepower, footcandles etc to lumens. I am trying to compare the intensity of different lighting fixtures in a catalog some are listed one way some the other.

Thanks,

1 footcandle = 10.76 lumen per square meter (lux)

Probably need to verify this...

A foot-candle is a lumen/ft²
A lux is a lumen/m²

Thanks for all the responses. They were very helpful. It's amazing sometimes when you have 3 or 4 handbooks but one particular item is just not in any of them.
