Candela to lux calculation

Calculation for Candela tp lux with the distance in feet

The value of illuminance Ev in lux (lx) is apparently equal to 10.76391 times the value of luminous intensity Iv measured in candela (cd), which is later divided by the square distance from the light source d2 in the square feet (ft2).

Ev(lx) = 10.76391 × Iv(cd) / (d(ft))2

Candela tp lux calculation with the distance in meters

The illuminance Ev in lux (lx) is apparently equal to the luminous intensity Iv which is measured in candela (cd), and lastly divided by the square distance from the light source d2 in the square meters (m2):

Ev(lx) = Iv(cd) / (d(m))2

lx = 10.76391 × cd / ft2
