A lux (symbol: lx) is the SI derived unit of illuminance (Eᵥ).
A phot is a unit of illuminance. One phot is equal to 104 lux (lx).
A foot-candle is a unit of illuminance. One foot-candle is equal to 10.763910417 lux (lx).
Divide the foot-candle value by 929.030400
phot = foot-candle / 929.030400
Multiply the phot value by 929.030400
foot-candle = phot x 929.030400
One phot (ph) is equal to 929.030400 foot-candle (fc)
1 phot (ph) = 929.030400 foot-candle (fc)
One foot-candle (fc) is equal to 0.001076 phot (ph)
1 foot-candle (fc) = 0.001076 phot (ph)
