About Pounds per US gallon
The pound per US gallon (lb/gal US) equals ≈119.826 kg/m³, the standard density unit in US petroleum refining, drilling, and petrochemical industries. Water at 60°F is 8.337 lb/gal; diesel 6.8-7.3 lb/gal; medium crude oil 7.1-8.0 lb/gal. Drilling mud weight per API RP 13B is specified in lb/gal (US) to control wellbore pressure. 1 lb/gal (US) ≈119.826 kg/m³ ≈7.481 lb/ft³.
About Milligrams per cubic metre
The milligram per cubic metre (mg/m³) equals 10⁻⁶ kg/m³, the reference unit for industrial occupational exposure limits (OELs). NIOSH REL for respirable crystalline silica is 0.05 mg/m³; OSHA PEL for Portland cement 15 mg/m³; ACGIH TLV for calcium carbonate dust 10 mg/m³. Numerically equal to µg/L, bridging airborne and aqueous analysis. 1 mg/m³ = 10⁻⁶ kg/m³ = 1 µg/L.
