About Illuminance Conversion

Illuminance measures the amount of luminous flux per unit area, indicating how much light falls on a surface. The SI unit is lux (lx), while foot-candles (fc) are commonly used in North America.

Typical illuminance values: moonlight ~1 lx, office lighting 300-500 lx, overcast day ~1000 lx, direct sunlight ~100,000 lx. Proper lighting design requires accurate illuminance calculations.
