Converting from Lumen per Square Meter (lm/m²) to Lumen per Square Foot (lm/ft²) | Illuminance

What is Lumen per Square Meter (lm/m²)

Lumen per square meter (lm/m²) is a unit of measurement used in illuminance, indicating the amount of light that falls on a surface per square meter. It is commonly used in lighting design and environmental studies to measure the level of brightness in a given area.

What is Lumen per Square Foot (lm/ft²)

Lumen per square foot (lm/ft²) is another unit of illuminance measurement that represents the light intensity per square foot of a surface. This unit is often used in applications where the area in question is measured in square feet rather than square meters.
