Convert Picocandelas to Millicandelas
Convert Picocandelas (pcd) to Millicandelas (mcd) instantly and accurately.
Conversion Formula
mcd = pcd × 1.000000000e-9
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 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.
