About Picocandelas per square metre
The picocandela per square metre (pcd/m²) equals 10⁻¹² cd/m². A theoretical subunit for precision photometric standards and astrophysical brightness modelling. Even the darkest measurable surfaces in calibrated laboratories have luminance many orders of magnitude above this scale. Used only in radiometric standard traceability chains. 1 pcd/m² = 10⁻¹² cd/m².
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.
