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 Lumens per square yard
The lumen per square yard (lm/yd²) equals 1/0.83612736 lx ≈ 1.196 lx. Used occasionally in UK outdoor area lighting specifications alongside foot-candles. A 3 lx minimum car-park standard equals ~2.5 lm/yd²; a 100 lx sports-field requirement ~84 lm/yd². 1 lm/yd² = 1/0.83612736 lx.
