About Candelas per square metre
The candela per square metre (cd/m²), informally called the nit, is the SI coherent unit of luminance. A typical laptop screen is 250-500 cd/m²; an HDR TV reaches 1 000-4 000 cd/m²; a clear blue sky is ~3 000-8 000 cd/m². Luminance is the photometric quantity directly perceived as brightness. 1 cd/m² = 1 nit.
About Skots
The skot (sk) equals 10⁻³/π cd/m² ≈ 3.183×10⁻⁴ cd/m², defined as one-thousandth of an apostilb. A legacy photometric unit from early German-language vision science. The dark-adapted human eye threshold is around 3×10⁻⁴ cd/m², close to 1 sk. Now obsolete; replaced by cd/m² in SI photometry. 1 sk = 10⁻³/π cd/m².
