About Millicandelas per square metre
The millicandela per square metre (mcd/m²) equals 10⁻³ cd/m². The luminance of a moonless night sky is ~10⁻³ cd/m²; a quarter-moon sky ~10⁻² cd/m². OLED screens in deep-black mode and unlit LCD panels measure a few mcd/m². Also the range for very dim indicator lamps. 1 mcd/m² = 10⁻³ cd/m².
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.
