Converting from Lumen per Square Foot (lm/ft²) to Lumen per Square Centimeter (lm/cm²) | Illuminance

What is Lumen per Square Foot (lm/ft²)

Lumen per square foot (lm/ft²) is a unit of illuminance that measures the amount of light falling on a surface per square foot. It is commonly used in lighting design and architecture to determine the brightness level of a given area.

What is Lumen per Square Centimeter (lm/cm²)

Lumen per square centimeter (lm/cm²) is another unit of illuminance used to measure light intensity on a surface in the metric system. It is particularly useful in scientific applications where precise measurements are required.

Conversion Formulas

The default conversion rate between lm/ft² and lm/cm² is:

• 1(lm/ft2)=0.001076391(lm/cm2)

• 1(lm/cm2)=929.0304(lm/ft2)

Additional conversion examples include:

• 2(lm/ft2)=0.002152782(lm/cm2)

• 2(lm/cm2)=1858.061(lm/ft2)

• 11(lm/ft2)=0.0118403(lm/cm2)

• 11(lm/cm2)=10219.33(lm/ft2)

• 14(lm/ft2)=0.01506947(lm/cm2)

• 14(lm/cm2)=13006.43(lm/ft2)

Examples

• If you have an illuminance measurement of 5 lm/ft², converting it to lm/cm² would be:

5(lm/ft2)×0.001076391=0.005381955(lm/cm2)

• Similarly, if you have an illuminance of 20 lm/cm², converting it to lm/ft² would be:

20(lm/cm2)×929.0304=18580.608(lm/ft2)
