FAQ
What is the conversion factor from klx to nox?
1 klx equals 1000000 nox. To convert, multiply the value in kilolux by 1000000.
How do I convert 1 klx to nox?
1 klx = 1.00000e+6 nox. For any value, multiply by 1000000.
How do I convert nox back to klx?
Divide by the same factor — or equivalently, multiply by 1e-6. So 1 nox = 1e-6 klx.
When would I need to convert kilolux to nox?
Illuminance conversions between klx and nox are used in lighting design, workplace safety assessments, and photographic exposure work. Lux is the SI standard for international codes; foot-candles remain common in US lighting specifications.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
