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 Meganits
The meganit (Mcd/m²) equals 10⁶ cd/m². The scale for extreme light sources: outdoor LED video walls at peak brightness reach 3-10 Mcd/m²; laser exit apertures are typically 10-10 000 Mcd/m²; the solar disc at zenith has luminance ≈1 600 Mcd/m² (1.6×10⁹ cd/m²). Used in laser safety and high-power illumination. 1 Mcd/m² = 10⁶ cd/m².
