Explanation

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.

Method & Reference

  • Method basis: exact conversion formula shown in Direct Answer.
  • Applied factor: 1 Phot = 10 Kilolux (using exact lux-based illuminance definitions).
  • Consistency rule: calculator output and table values use the same constants and rounding policy.

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.
