About Pounds per UK gallon

The pound per UK gallon (lb/gal UK) equals ≈99.776 kg/m³, based on the avoirdupois pound and the UK gallon (4.54609 L). Used historically in British petroleum refining and Admiralty fuel specifications; the original UK specific-gravity tables reference lb/gal UK. Still encountered in some Commonwealth marine and aviation standards. 1 lb/gal (UK) ≈99.776 kg/m³ ≈6.228 lb/ft³.

About Nanograms per cubic metre

The nanogram per cubic metre (ng/m³) equals 10⁻¹² kg/m³, the resolution floor of atmospheric radionuclide and trace-contaminant monitoring. Sr-90 fallout from nuclear testing is measured in ng/m³; EPA Method TO-14A quantifies volatile organic compounds at this level. HEPA-filtered clean-room air achieves particulate densities of 1-100 ng/m³. 1 ng/m³ = 10⁻¹² kg/m³ = 10⁻³ µg/m³.
