Convert Nanocandelas to Gigacandelas
Convert Nanocandelas (ncd) to Gigacandelas (Gcd) instantly and accurately.
Conversion Formula
Gcd = ncd × 1.000000000e-18
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.
About Gigacandelas
The gigacandela (Gcd) equals 10⁹ cd. The scale for extremely powerful directed beams and for astrophysical luminous intensity comparisons. A nuclear fireball at peak emission approaches this range; high-power pulsed laser outputs in the visible spectrum can reach Gcd-level peak intensity in the beam axis. 1 Gcd = 10⁹ cd.
