Candela per square meter (nit) quick reference
| Candela per square meter (nit) | Candela per square foot | Foot-lambert | Kilocandela per square meter |
|---|---|---|---|
| 1 cd/m² | = 0.09290304 cd/ft² | ≈ 0.291863508 fL | = 0.001 kcd/m² |
| 10 cd/m² | = 0.9290304 cd/ft² | ≈ 2.91863508 fL | = 0.01 kcd/m² |
| 100 cd/m² | = 9.290304 cd/ft² | ≈ 29.1863508 fL | = 0.1 kcd/m² |
| 1000 cd/m² | = 92.90304 cd/ft² | ≈ 291.863508 fL | = 1 kcd/m² |
Where the candela per square meter fits
The next smaller luminance unit is the apostilb (asb). 1 cd/m² ≈ 3.141592654 asb, and 1 asb ≈ 0.3183098862 cd/m².
The next larger luminance unit is the foot-lambert (fL). 1 cd/m² ≈ 0.291863508 fL, and 1 fL ≈ 3.4262591 cd/m².
