Nit to Foot-lambert (Nit to Foot-lambert)
Result
0.291863508 Foot-lambert
Formula
Foot-lambert = Nit × 0.291863508
1 Nit = 0.291863508 Foot-lambert, and 1 Foot-lambert = 3.4262591 Nit.
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 Nit × 0.291863508 = 0.29186351 Foot-lambert
- 10 Nit × 0.291863508 = 2.9186351 Foot-lambert
- 100 Nit × 0.291863508 = 29.186351 Foot-lambert
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.
