Explanation

Multiply by 10 because 1 ph = 10000 lux and 1 klx = 1000 lux.

Method & Reference

  • Method basis: exact conversion formula shown in Snapshot.
  • 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.

Questions & answers

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.
