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.

About Kilocandelas per square metre

The kilocandela per square metre (kcd/m²) equals 1 000 cd/m². The scale for HDR displays and high-brightness monitors: VESA DisplayHDR 1000 requires 1 kcd/m² peak; professional HDR mastering monitors reach 1-4 kcd/m²; an overcast sky measures ~3-8 kcd/m²; a fluorescent tube ~7 kcd/m². 1 kcd/m² = 10³ cd/m².
