- 1 lx = 0.001 klx
- Example: convert 15 klx to lx: 15 klx = 15 × 1000 lx = 15000 lx
Formula
lx = klx × 1000
Derivation from SI units:
- 1 klx = 10³ lx.
- 1 lx = 1 lm/m².
Both units are defined exactly, so the factor is exact. Kilolux definition: kilolux; Lux definition: lux.
Worked examples
- A reading of 20 klx converts to 20000 lx.
20 klx × 1000 = 20000 lx - A value of 75 klx is 75000 lx.
75 klx × 1000 = 75000 lx
