## Lumens to lux calculation formula

#### Calculation with area in square feet

So The illuminance Ev in lux (lx) is equal to 10.76391 times the luminous flux ΦV in lumens (lm) divided by the surface area A in square feet (ft2).

Ev(lx) = 10.76391 × ΦV(lm) / A(ft2)

So The illuminance Ev in lux (lx) is equal to 10.76391 times the luminous flux ΦV in lumens (lm) divided by 4 times pi times the squared sphere radius r in feet (ft).

Ev(lx) = 10.76391 × ΦV(lm) / (4⋅π⋅r(ft)2)

#### Calculation with area in square meters

So The illuminance Ev in lux (lx) is equal to the luminous flux ΦV in lumens (lm) divided by the surface area A in square meters (m2).

Ev(lx) = ΦV(lm) / A(m2)

The illuminance Ev in lux (lx) is equal to the luminous flux ΦV in lumens (lm) divided by 4 times pi times the squared sphere radius r in meters (m):

Ev(lx) = ΦV(lm) / (4⋅π⋅r 2(m2))
