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.

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.
