SwitchExplanation
Formula: Kilolux = Phot × 10. Why: phot is tied exactly to lux through the square-centimeter to square-meter area relationship, so the route normalizes through lux before applying the target unit.
Phot (ph): a CGS illuminance unit equal to one lumen per square centimeter, which is exactly 10,000 lux.
Kilolux (klx): an illuminance unit equal to 1,000 lux, used for bright lighting conditions, exposure references, and high-illumination environments.
This route is useful when comparing phot-based CGS illuminance values against modern lux-based references in laboratory, optical, and legacy technical material.
This conversion is purely multiplicative because both units reduce through lux using fixed illuminance definitions with no offset.

Frequently Asked Questions
What is 1 phot in kilolux?
1 Phot equals 10 Kilolux on this page.
Does this Phot to Kilolux page use the exact lux relationship for phot?
Yes. Phot routes use the exact relationship 1 phot = 10,000 lux through one lux normalization path, so CGS and modern lighting references stay consistent across the page.
When would I convert phot to kilolux?
This route is useful when comparing phot-based CGS illuminance values against modern lux-based references in laboratory, optical, and legacy technical material.
How do I reverse Phot to Kilolux?
Use the mirror Kilolux to Phot route; it applies the inverse relationship with the same illuminance assumptions.
