Conversion Formula
ncd = pcd × 0.001
About Picocandelas
The picocandela (pcd) equals 10⁻¹² cd. A theoretical subunit used only in precision photometric standard traceability and single-photon detector characterisation. The faintest LED indicator in standby mode (~10 µcd) is one million times brighter. Appears in calibration chain documentation. 1 pcd = 10⁻¹² cd.
About Nanocandelas
The nanocandela (ncd) equals 10⁻⁹ cd. The scale of extremely faint bioluminescence: a single luciferin-luciferase reaction emits around 1-10 ncd; dark-adapted firefly flashes peak at a few hundred ncd. Also the range for cooled avalanche-photodiode sensitivity characterisation. 1 ncd = 10⁻⁹ cd.
