How to Convert Kilolux to Foot-candle
- 1 klx = 92.90304 fc
- 1 fc = 0.01076391042 klx
- Example: convert 15 klx to fc: 15 klx = 15 × 92.90304 fc = 1393.5456 fc
Formula
fc = klx × 92.90304
Derivation from SI units:
- 1 klx = 10³ lx.
- 1 fc = 1 lm/ft² = 1/0.09290304 lx ≈ 10.7639 lx.
- 1 klx = 1000 lx ÷ 10.76391041671 lx per fc = 92.90304 fc
Both units are defined exactly, so the factor is exact. Kilolux definition: kilolux; Foot-candle definition: foot-candle.
Worked examples
- A reading of 20 klx converts to 1858.0608 fc.
20 klx × 92.90304 = 1858.0608 fc - A value of 75 klx is 6967.728 fc.
75 klx × 92.90304 = 6967.728 fc
