FAQ
What is the conversion factor from klx to lx?
1 klx equals 1000 lx. To convert, multiply the value in kilolux by 1000.
How do I convert 1 klx to lx?
1 klx = 1000 lx. For any value, multiply by 1000.
How do I convert lx back to klx?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 lx = 0.001 klx.
When would I need to convert kilolux to lux?
Illuminance conversions between klx and lx 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).
