### Lux to candela calculation with distance in feet

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

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

Iv(cd) = 0.09290304 × Ev(lx) × (d(ft))2

So

candela = 0.09290304 × lux × square feet

Or

cd = 0.09290304 × lx × ft2

### Lux to candela calculation with distance in meters

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

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

Iv(cd) = Ev(lx) × (d(m))2

So

candela = lux × square meters

Or

cd = lx × m2
