Converting from Lux (lx) to Lumen per Square Centimeter (lm/cm²) | Illuminance

What is Lux (lx)

Lux (lx) is a unit of measurement used to quantify illuminance, which is the amount of light that falls on a surface. It is defined as one lumen per square meter. Lux is commonly used to measure the intensity of light in various applications, such as lighting design, photography, and outdoor lighting.

What is Lumen per Square Centimeter (lm/cm²)

Lumen per Square Centimeter (lm/cm²) is another unit of illuminance that represents the amount of light that hits a specific area. This unit is a more localized measure of illuminance compared to lux, as it focuses on the light intensity per square centimeter rather than per square meter.

Conversion Formulas

The default conversion between lux (lx) and lumen per square centimeter (lm/cm²) is:

• 1 (lx) = 0.0001 (lm/cm²)
• 1 (lm/cm²) = 10000 (lx)

Other conversions include:

• 5 (lx) = 0.0005 (lm/cm²) or 5 (lm/cm²) = 50000 (lx)
• 2 (lx) = 0.0002 (lm/cm²) or 2 (lm/cm²) = 20000 (lx)
• 7 (lx) = 0.0007 (lm/cm²) or 7 (lm/cm²) = 70000 (lx)

Examples

1. Convert 10 lux to lumen per square centimeter (lm/cm²):

10 lx×0.0001=0.001 lm/cm²

2. Convert 3 lumen per square centimeter (lm/cm²) to lux:

3 lm/cm²×10000=30000 lx
