How to Convert Lumens per Square Inch to Kilophots
The lumen per square inch and kilophot are both units of illuminance. 1 kilophot equals 6451.6 lumens per square inch. This means to convert lumens per square inch to kilophots, you divide by 6451.6.
Formula
Step-by-Step Example
Convert 5 lm/in² to kilophots:
We need to convert lumens per square inch to kilophots
Since 1 kph = 6451.6 lm/in², divide by 6451.6
5 ÷ 6451.6 = 0.0007750016
5 lm/in² = 0.0007750016 kph

About These Units
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.
Kilophot (kph)
A kilophot (kph) equals 1,000 phots or 10,000,000 lux (10 megalux). Represents extreme illumination far beyond natural conditions. Theoretical unit for laser and concentrated light applications. Direct sunlight maximum is only about 0.01 kilophots.
