A question for the ENGINEERS!

Whats a foot candle?

It's super technical.

a unit of illumination (now little used) equal to that given by a source of one candela at a distance of one foot (equivalent to one lumen per square foot or 10.764 lux)

Edit: the internet says it's little used, but I still see it in a lot of station and rail yard lighting design criteria. I guess that's because railroads always act like it's 1902.

Man, we use some weird units of measure in civil engineering in the United States. Foot-candles? Acre-feet? I'm glad I'm mostly in bridges and rail so I can deal with normal things like kips and Million Gross Tons.

Acre-feet is so much cooler than M^3.

I see foot candle whenever i'm dealing with an insurance claim/lawsuit arising from inadequate lighting. I think it's referenced in the IBC.
