FAQ
What is the conversion factor from fc to klx?
1 fc equals 0.01076391 klx. To convert, multiply the value in foot-candles by 0.01076391.
How do I convert 1 fc to klx?
1 fc = 0.0107639 klx. For any value, multiply by 0.01076391.
How do I convert klx back to fc?
Divide by the same factor — or equivalently, multiply by 92.90304. So 1 klx = 92.903 fc.
When would I need to convert foot-candle to kilolux?
Illuminance conversions between fc and klx 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).
