## Lux to candela calculation

#### 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* *×* E*_{v(lx)} × (*d*_{(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)} × (*d*_{(m)})^{2}
