Convert Lumen per Square Centimeter to Phot
Input the number of lumens per square centimeter you want to convert to phots.
How to Convert Lumens per Square Centimeter to Phots
The lumen per square centimeter and phot are both units of illuminance. By definition, 1 lumen per square centimeter equals exactly 1 phots. This means to convert lumens per square centimeter to phots, you multiply by 1.
Formula
Step-by-Step Example
Convert 5 lm/cm² to phots:
We need to convert lumens per square centimeter to phots
Since 1 lm/cm² = 1 ph, multiply by 1
5 × 1 = 5
5 lm/cm² = 5 ph

About These Units
Lumen per Square Centimeter (lm/cm²)
Lumens per square centimeter (lm/cm²) equals 10,000 lux or 1 phot. Used in scientific contexts for high-intensity illumination. One lm/cm² represents intense light levels found in specialized applications like projection systems and concentrated solar power.
Phot (ph)
The phot (ph) is the CGS unit of illuminance equal to 10,000 lux or 1 lumen per square centimeter. Very bright: full sunlight is about 10 phots. Found in older scientific literature. One phot = 929 foot-candles. Largely replaced by lux in modern usage.
