Converting from Lux (lx) to Lumen per Square Meter (lm/m²) | Illuminance

What is Lux (lx)

Lux (lx) is a unit of measurement used to quantify illuminance, which represents the amount of visible light that falls on a surface per unit area. In simpler terms, lux measures the brightness of the light that illuminates a specific area.

What is Lumen per Square Meter (lm/m²)

Lumen per Square Meter (lm/m²) is another unit that quantifies illuminance. It specifically measures the amount of luminous flux (in lumens) that falls on a given surface area of one square meter. This unit is commonly used in various lighting applications to determine the intensity of illumination provided by a light source.

Conversion Formulas

The default conversion between Lux and Lumen per Square Meter is:

• 1 (lx) = 1 (lm/m²)
• 1 (lm/m²) = 1 (lx)

Other examples of conversions include:

• 3 (lx) = 3 (lm/m²)
• 3 (lm/m²) = 3 (lx)
• 12 (lx) = 12 (lm/m²)
• 12 (lm/m²) = 12 (lx)
• 7 (lx) = 7 (lm/m²)
• 7 (lm/m²) = 7 (lx)

To convert from Lux to Lumen per Square Meter, use the following formula:

Lumen per Square Meter (lm/m²)=Lux (lx)

Examples

1. If you have an illuminance of 50 lux, the equivalent value in lumen per square meter would also be 50 lm/m².
2. For an illuminance of 100 lux, the value in lumen per square meter remains the same at 100 lm/m².
