Is there a conversion formula to convert EV values from a light meter to foot candles?

Convert to lux first (EV native units are metric); lux=2.5*2EV and.... FC=lux/10.7639 or.... FC=0.2323*2EV Example: EV=10, lux= 2.5*210, 210= 1024, so.. 2.5*1024= 2560lux, or.. 0.2323*1024=238FC for non-math types 2^4 is the same as 24= 2 raised to the power of 4.. e.g. 24= 2*2*2*2=16
