About Gram per cubic centimeter (g/cm³)
A CGS-system density unit numerically equal to specific gravity relative to water at 4 °C (water = 1.000 g/cm³ by the original 1795 kilogram definition). 1 g/cm³ = 1,000 kg/m³, making the conversion between this CGS unit and the SI trivial. Widely used in geology (sedimentary rock 2.0-2.7 g/cm³, granite 2.65-2.75, basalt 2.8-3.0), crystallography and gemology (diamond 3.52 g/cm³, ruby and sapphire 4.00, opal 1.98-2.25 — density is the primary non-destructive ID method for cut gemstones), polymer chemistry (HDPE 0.94-0.97, PP 0.85-0.95, PET 1.37-1.45, PVC 1.30-1.45), and the wine, beer, and spirits industry where density is reported as specific gravity (final-gravity vs original-gravity readings drive ABV calculation). Petroleum: API gravity is defined directly from g/cm³ as °API = (141.5 / SG) − 131.5.
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.
