### Candela to lux calculation

#### Candela tp lux calculation with distance in feet

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}

#### Candela tp lux calculation with distance in meters

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}
