How to convert luminous intensity in candela (cd) to illuminance in lux (lx).

You can calculate lux from candela and distance from light source.

You can't convert candela to lux, since lux and candela do not represent the same quantity.

The illuminance *E*_{v} in
lux (lx) is equal
to 10.76391 times the luminous intensity *I*_{v} in candela (cd),

divided by the square distance from the light source *d*^{2}
in square feet (ft^{2}):

*E*_{v(lx)} =
10.76391 ×* I*_{v(cd)} / (*d*_{(ft)})^{2}

_{So}

lux = 10.76391 ×* *candela / square feet

_{Or}

lx = 10.76391 ×* *cd / ft^{2}

The illuminance *E*_{v} in
lux (lx) is equal
to the luminous intensity *I*_{v} in candela (cd),

divided by the square distance from the light source *d*^{2} in
square meters (m^{2}):

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

_{So}

lux = candela / square meters

_{Or}

lx = cd / m^{2}
