Convert Nanocandelas to Millicandelas
Convert Nanocandelas (ncd) to Millicandelas (mcd) instantly and accurately.
Conversion Formula
mcd = ncd × 1.000000000e-6
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 Millicandelas
The millicandela (mcd) equals 10⁻³ cd. The most common unit in LED datasheets: a standard 3 mm through-hole LED has 5-500 mcd at 20 mA; a high-efficiency indicator LED 500-2 000 mcd; signal LEDs for visible-range indicators typically 10-200 mcd. The IEC standard range for low-current indicators. 1 mcd = 10⁻³ cd.
