Converting from Lumen per Square Meter (lm/m²) to Lumen per Square Inch (lm/in²) | Illuminance

What is Lumen per Square Meter (lm/m²)

Lumen per square meter (lm/m²) is a unit of measurement that represents the illuminance on a surface in lumens per square meter. It is commonly used to quantify the amount of light falling on a given area.

What is Lumen per Square Inch (lm/in²)

Lumen per square inch (lm/in²) is another unit of illuminance measurement that indicates the amount of light incident on a surface in lumens per square inch. This unit is often used in specific applications where smaller areas need to be illuminated.

Conversion Formulas

The conversion between lumen per square meter (lm/m²) and lumen per square inch (lm/in²) can be calculated using the following formulas:

lm/in²=lm/m²×0.00064516

lm/m²=lm/in²×1550.003

Examples

1. Converting 16 lm/m² to lm/in²:

16lm/m²=0.01032256lm/in²

2. Converting 5 lm/m² to lm/in²:

5lm/m²=0.0032258lm/in²

3. Converting 4 lm/in² to lm/m²:

4lm/in²=6200.012lm/m²
