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

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

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

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* *×*
E*_{v(lx)} × (*d*_{(ft)})^{2}

_{So}

candela = 0.09290304* *×*
*lux × square feet

_{Or}

cd = 0.09290304* *×*
*lx × ft^{2}

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)} × (*d*_{(m)})^{2}

_{So}

candela = lux × square meters

_{Or}

cd = lx × m^{2}
