Foot-lambert to Candela/m² (Foot-lambert to Candela/m²)
Result
3.4262591 Candela/m²
Formula
Candela/m² = Foot-lambert × 3.4262591
1 Foot-lambert = 3.4262591 Candela/m², and 1 Candela/m² = 0.291863508 Foot-lambert.
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-lambert × 3.4262591 = 3.4262591 Candela/m²
- 10 Foot-lambert × 3.4262591 = 34.262591 Candela/m²
- 100 Foot-lambert × 3.4262591 = 342.62591 Candela/m²
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.
