Explanation

Multiply by 0.1 because 1 klx = 1000 lux and 1 ph = 10000 lux.

Method & Reference

Method basis: exact conversion formula shown in Snapshot.
Applied factor: 1 Kilolux = 0.1 Phot (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 kilolux in phot?

1 Kilolux equals 0.1 Phot on this page.

Does this Kilolux to Phot 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 kilolux to phot?

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 Kilolux to Phot?

Use the mirror Phot to Kilolux route; it applies the inverse relationship with the same illuminance assumptions.
