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 Candelas per square metre
The candela per square metre (cd/m²), informally called the nit, is the SI coherent unit of luminance. A typical laptop screen is 250-500 cd/m²; an HDR TV reaches 1 000-4 000 cd/m²; a clear blue sky is ~3 000-8 000 cd/m². Luminance is the photometric quantity directly perceived as brightness. 1 cd/m² = 1 nit.
