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

What is Lumen per Square Foot (lm/ft²)

Lumen per Square Foot (lm/ft²) is a unit of measurement used to quantify the amount of visible light illuminating a surface area in a given space. It measures the intensity of light falling on a specific area in square feet.

What is Lux (lx)

Lux (lx) is the standard metric unit of illuminance, which measures the amount of visible light that falls on a specific area in square meters. It indicates the brightness of the light that is perceived by the human eye.

Conversion Formulas

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

• Lux (lx)=Lumen per Square Foot (lm/ft²)×10.76391

• Lumen per Square Foot (lm/ft²)=Lux (lx)×0.09290304

Examples

1. Converting 12 lm/ft² to lx:

12 lm/ft²=12×10.76391=129.1669 lx

2. Converting 14 lx to lm/ft²:

14 lx=14×0.09290304=1.300643 lm/ft²

3. Converting 16 lm/ft² to lx:

16 lm/ft²=16×10.76391=172.2226 lx

You can use these conversion formulas to easily switch between Lumen per Square Foot (lm/ft²) and Lux (lx) for various lighting applications.
