Converting from Lux (lx) to Lumen per Square Foot (lm/ft²) | Illuminance

What is Lux (lx)

Lux (lx) is a unit of measurement for illuminance, which quantifies the intensity of light that falls on a surface. One lux is equal to one lumen per square meter, indicating the amount of light intensity present within a given area.

What is Lumen per Square Foot (lm/ft²)

Lumen per Square Foot (lm/ft²) is another unit used to measure illuminance. It represents the amount of lumens falling on each square foot of a surface, indicating the brightness of light experienced within that area.

Conversion Formulas

The relationship between Lux (lx) and Lumen per Square Foot (lm/ft²) can be expressed using the following conversion formulas:

• 1(lx)=0.09290304(lm/ft²)

• 1(lm/ft²)=10.76391(lx)

Examples

To illustrate the conversion process:

1. If you have 7 lux:

   • This is equivalent to 0.6503213 lumens per square foot.

2. If you have 11 lux:

   • This is equivalent to 1.021933 lumens per square foot.

3. If you have 9 lux:

   • This is equivalent to 0.8361274 lumens per square foot.

By understanding these conversion formulas and examples, you can easily convert illuminance values between Lux and Lumen per Square Foot.
