to get the luminous intensity in candela:

Lux to candela calculation

The luminous intensity I_v in candela (cd) is equal to 0.09290304 times the illuminance E_v in lux (lx),

times the square distance from the light source d² in square feet (ft²):

I_v(cd) = 0.09290304 × E_v(lx) × (d_(ft))²

The luminous intensity I_v in candela (cd) is equal to the illuminance E_v in lux (lx),

times the square distance from the light source d² in square meters (m²):

I_v(cd) = E_v(lx) × (d_(m))²

Enter illuminance in lux:		lx
Enter distance and select feet or meters:

Luminous intensity 結果 in candela:		cd
