### Lux to candela calculation with distance in feet

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 *d*^{2}
in square feet (ft^{2}):

*I*_{v(cd)} =
0.09290304* *Ã—*
E*_{v(lx)} Ã— (*d*_{(ft)})^{2}

_{So}

candela = 0.09290304* *Ã—*
*lux Ã— square feet

_{Or}

cd = 0.09290304* *Ã—*
*lx Ã— ft^{2}

### Lux to candela calculation with distance in meters

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 *d*^{2} in
square meters (m^{2}):

*I*_{v(cd)} =
*E*_{v(lx)} Ã— (*d*_{(m)})^{2}

_{So}

candela = lux Ã— square meters

_{Or}

cd = lx Ã— m^{2}
