Luminous intensity in candela (cd) to illuminance in lux (lx) calculator and how to calculate.
Enter the luminous intensity in candela, distance from light source, select feet or meters and press the Calculate button to get the illuminance in lux:
The illuminance Ev in lux (lx) is equal to 10.76391 times the luminous intensity Iv in candela (cd),
divided by the square distance from the light source d2 in square feet (ft2):
Ev(lx) = 10.76391 × Iv(cd) / (d(ft))2
The illuminance Ev in lux (lx) is equal to the luminous intensity Iv in candela (cd),
divided by the square distance from the light source d2 in square meters (m2):
Ev(lx) = Iv(cd) / (d(m))2
