About These Units
Kilocandela per Square Meter (kcd/m²)
A kilocandela per square meter (kcd/m² or kilonit) equals 1,000 nits. Used for bright outdoor displays, searchlights, and solar measurements. Bright overcast sky: 2-5 kcd/m². Direct sunlight on white surface: 30+ kcd/m². Premium HDR displays reach 2-4 kcd/m².
Apostilb (asb)
The apostilb (asb) equals 1/π cd/m² ≈ 0.318 nits. Represents the luminance of a perfect diffuser illuminated by 1 lux. Also called blondel. One apostilb ≈ 0.0929 foot-lamberts. Useful in theoretical calculations involving diffuse reflection.
