Foot-candle to Lux (Foot-candle to Lux)
Result
10.76391042 Lux
Formula
Lux = Foot-candle × 10.76391042
1 Foot-candle = 10.76391042 Lux, and 1 Lux = 0.09290304 Foot-candle.
Luminance is how bright a surface looks: 1 nit = 1 cd/m², and a foot-lambert is 1/π cd/ft² (3.4262591 cd/m²). Illuminance is light falling on a surface: 1 lux = 1 lumen/m², and a foot-candle is 1 lumen/ft² (10.7639104 lux).
Worked examples
- 1 Foot-candle × 10.76391042 = 10.76391 Lux
- 10 Foot-candle × 10.76391042 = 107.6391 Lux
- 100 Foot-candle × 10.76391042 = 1,076.391 Lux
Common mistakes
- Luminance (screens, nits) and illuminance (lux meters, room lighting) are different quantities and do not convert into each other.
- Lumens measure a lamp's total output; turning lumens into lux needs the illuminated area.
