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 Candelas per square inch
The candela per square inch (cd/in²) equals 1/0.00064516 cd/m² ≈ 1 550 cd/m². Used in US LED and CRT datasheets when citing luminance of small emitter areas. A high-brightness packaged LED chip in a focussed-beam configuration can reach 1-20 cd/in². 1 cd/in² = 1/(0.0254²) cd/m².
