Candela to lux calculation

Candela to lux calculation with distance in feet

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 光照 source d2 in square feet (ft2):

Ev(lx) = 10.76391 × Iv(cd) / (d(ft))2

Candela to lux calculation with distance in meters

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

divided by the square distance from the 光照 source d2 in square meters (m2):

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