Formula
Step-by-Step Example
Convert 5 lm/m² to lumens per square inch:
We need to convert lumens per square meter to lumens per square inch
Since 1 lm/in² = 1550.0031 lm/m², divide by 1550.0031
5 ÷ 1550.0031 = 0.0032258
5 lm/m² = 0.0032258 lm/in²

About These Units
Lumen per Square Meter (lm/m²)
Lumens per square meter (lm/m²) is the defining formula for lux: illuminance equals luminous flux divided by area. One lux = one lumen per square meter. Used in lighting calculations: required lumens = lux × area. Essential for lighting design and energy efficiency.
Lumen per Square Inch (lm/in²)
Lumens per square inch (lm/in²) equals 1,550 lux or 144 foot-candles. Used for high-intensity illumination of small areas: display lighting, inspection systems, and microscopy. One lm/in² = 144 lm/ft². Rarely used; lux or foot-candles preferred.
