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 Foot-lamberts
The foot-lambert (fL) equals 1/(π×0.09290304) cd/m² ≈ 3.426 cd/m², the luminance of a perfect diffuse surface emitting 1 lumen per square foot. The SMPTE standard for cinema screen luminance is 14 fL (≈48 cd/m²); home projectors are rated 10-35 fL. Still standard in US cinema and theatre engineering. 1 fL = 1/(π×ft²) cd/m².
