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 Lamberts
The lambert (L) equals 10⁴/π cd/m² ≈ 3 183 cd/m², the luminance of a perfect diffuse surface emitting 1 lumen per square centimetre. The CGS practical luminance unit. An incandescent lamp globe at 3 200 K has luminance ~1 L; a clear sky is ~0.94 L. Superseded by cd/m² in SI photometry. 1 L = 10⁴/π cd/m².
