About These Units
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.
Candela per Square Meter (cd/m²)
Candelas per square meter (cd/m²) is the SI unit of luminance, measuring brightness of a surface. Also called "nit." Laptop screen: 250-400 cd/m², HDR TV peak: 1,000-4,000 cd/m², sun at horizon: 600,000 cd/m². Critical for display specifications and HDR standards.
