About Millilamberts

The millilambert (mL) equals 10/π cd/m² ≈ 3.183 cd/m². Historically used in the United States to specify projection screen luminance and oscilloscope phosphor brightness. A projection screen with luminance 1 mL ≈ 3.18 cd/m². Largely superseded by cd/m² and foot-lamberts in modern display standards. 1 mL = 10/π cd/m².

About Microcandelas per square metre

The microcandela per square metre (µcd/m²) equals 10⁻⁶ cd/m². Used in precision dark-sky photometry and in measuring the luminance of unlit passive surfaces. OLED deep-black levels are typically 0.0001-0.01 cd/m², about 100-10 000 times larger than this scale. 1 µcd/m² = 10⁻⁶ cd/m².
