Kilocandela per square meter quick reference
| Kilocandela per square meter | Candela per square meter (nit) | Foot-lambert | Stilb |
|---|---|---|---|
| 1 kcd/m² | = 1000 cd/m² | ≈ 291.863508 fL | = 0.1 sb |
| 10 kcd/m² | = 10000 cd/m² | ≈ 2918.63508 fL | = 1 sb |
| 100 kcd/m² | = 100000 cd/m² | ≈ 29186.3508 fL | = 10 sb |
| 1000 kcd/m² | = 1000000 cd/m² | ≈ 291863.508 fL | = 100 sb |
Where the kilocandela per square meter fits
The next smaller luminance unit is the candela per square foot (cd/ft²). 1 kcd/m² = 92.90304 cd/ft², and 1 cd/ft² ≈ 0.01076391042 kcd/m².
The next larger luminance unit is the candela per square inch (cd/in²). 1 kcd/m² = 0.64516 cd/in², and 1 cd/in² ≈ 1.5500031 kcd/m².
