About Pound per cubic foot (lb/ft³)
An imperial density unit (lbm/ft³, sometimes #/ft³) dominant in US construction, civil engineering, and oil-and-gas industries. Reference values: fresh water at 60 °F is 62.37 lb/ft³ (commonly rounded to 62.4 for engineering), sea water 64.0 lb/ft³, normal-weight concrete 150 lb/ft³ (ACI 318 default), lightweight structural concrete 105-125 lb/ft³, structural steel 490 lb/ft³, asphalt pavement 140-150 lb/ft³, lumber framing (SPF dimensional) 30-35 lb/ft³, fiberglass batt insulation 0.5-2.0 lb/ft³. Lb/ft³ appears explicitly in ASCE 7 dead-load tables (the US loading code), US residential plumbing water-hammer calculations, mineral-wool / fiberglass insulation product spec sheets, drilling-fluid specs (mud weight quoted as ppg = lb/gal but pressure-gradient math uses lb/ft³), and HVAC duct-design air-density corrections for altitude. Convert lb/ft³ to kg/m³ by multiplying by 16.018; to g/cm³ by multiplying by 0.01602.
About Kilogram per cubic meter (kg/m³)
The SI derived unit of density (ISO 80000-4 §4-2), expressing mass per unit volume. Kg/m³ is the universal scientific and engineering working unit — fluid mechanics, structural design, materials selection, chemistry, geophysics, and CFD all express density in kg/m³. Reference values: water at 4 °C is 1,000.00 kg/m³ (the historical kilogram definition), air at sea-level/15 °C is 1.225 kg/m³ (ICAO ISA), structural steel ~7,850 kg/m³, aluminum alloys ~2,700 kg/m³, normal-weight concrete ~2,400 kg/m³ (lightweight ~1,800), lead 11,340 kg/m³, tungsten 19,250 kg/m³, osmium 22,590 kg/m³ (the densest naturally-occurring element), liquid mercury 13,534 kg/m³. Materials-property databases (MatWeb, NIST MMP, ASM Handbook, Granta Selector) tabulate every alloy and plastic in kg/m³. Convert to g/cm³ by dividing by 1,000; to lb/ft³ by dividing by 16.02; to slug/ft³ by dividing by 515.4.
