About Nanocandelas per square metre
The nanocandela per square metre (ncd/m²) equals 10⁻⁹ cd/m². Represents luminance at the threshold of cooled photomultiplier tubes and avalanche photodiode detectors. The darkest OLED black levels (~10⁻⁴ cd/m²) are still five orders of magnitude brighter; this unit is used in single-photon counting photometry. 1 ncd/m² = 10⁻⁹ cd/m².
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 Largely superseded by cd/m² and foot-lamberts in modern display standards. 1 mL = 10/π cd/m².
