Unit lm/ft²
Name lumen per square foot
Category Illuminance
Details Lm/ft² (lumen per square foot) is a unit used to measure illuminance in the field of lighting design and engineering. Illuminance refers to the amount of light that falls on a surface, and it helps determine how well-lit the surface is for various tasks and activities. The lumen is a unit of luminous flux, which is the total amount of visible light emitted by a light source, while the square foot is a unit of area.

When combined, lm/ft² indicates the amount of luminous flux incident on one square foot of a surface. In this context, the higher the lm/ft² value, the more well-illuminated the surface is.

It is important to note that lm/ft² is an imperial unit for illuminance measurement. The corresponding SI (metric) unit is lux (lx), which is expressed as lumens per square meter (lm/m²). To convert lm/ft² to lux, multiply the value by 10.764.
