Conversion Formula
Mlx = nlx × 1.000000000e-15
About Nanolux
The nanolux (nlx) equals 10⁻⁹ lx. Astronomical night-sky scale: the zodiacal band contributes ~10-50 nlx; airglow ~150 nlx; the Milky Way core ~100 nlx. The absolute human eye threshold is around 100 nlx. Used in night-sky quality metrics and photomultiplier tube calibration. 1 nlx = 10⁻⁹ lx.
About Megalux
The megalux (Mlx) equals 10⁶ lx. Reached only by extreme short-range sources: a short-arc xenon lamp at 5 cm produces ~1-10 Mlx; pulsed photographic strobes at close range several Mlx. The full solar disc on Earth's surface gives ~100 klx - far below 1 Mlx. 1 Mlx = 10⁶ lx.
