A lux (symbol: lx) is the SI derived unit of illuminance (Eᵥ).
A Lumen per square inch is a unit of illuminance. One Lumen per square inch is equal to 1550.0031 Lux (SI unit).
A foot-candle is a unit of illuminance. One foot-candle is equal to 10.763910417 lux (lx).
Divide the foot-candle value by 144.000000
lumen per square inch = foot-candle / 144.000000
Multiply the lumen per square inch value by 144.000000
foot-candle = lumen per square inch x 144.000000
One lumen per square inch (lm/in²) is equal to 144.000000 foot-candle (fc)
1 lumen per square inch (lm/in²) = 144.000000 foot-candle (fc)
One foot-candle (fc) is equal to 0.006944 lumen per square inch (lm/in²)
1 foot-candle (fc) = 0.006944 lumen per square inch (lm/in²)
