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.
About Picolux
The picolux (plx) equals 10⁻¹² lx. A theoretical subunit used only in precision photometric standard traceability. Even the faintest measurable natural illuminance - starlight on a moonless night at ~200 nlx - is 200 billion times brighter. Appears only in SI reference chains for calibration laboratories. 1 plx = 10⁻¹² lx.
