About Lumens per square inch
The lumen per square inch (lm/in²) equals 1/0.00064516 lx ≈ 1 550 lx. Used in US optics and LED backlight datasheets when specifying output over small aperture areas. Rare in general lighting but found in US optical engineering catalogs and LCD backlight specifications. 1 lm/in² = 1/0.00064516 lx.
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.
