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 milliliter (g/mL)

A density unit numerically identical to g/cm³ (since 1 mL ≡ 1 cm³ exactly by SI definition). Gram per milliliter is the universal working unit in analytical chemistry, pharmacy, biology, and clinical laboratory medicine: liquid reagent specifications, drug formulation density data, USP / EP / JP / BP / IP pharmacopoeial monographs, hydrometer-based density measurement, and solution-preparation calculations (where mass-volume conversions are routine) all use g/mL. The CRC Handbook of Chemistry and Physics tabulates several thousand pure-liquid densities in g/mL at 20-25 °C. Pharmaceutical examples: glycerin 1.261 g/mL, propylene glycol 1.036 g/mL, USP-grade ethanol (96% v/v) 0.8161 g/mL at 20 °C. Lab/clinical examples: human blood 1.060 g/mL, urine 1.005-1.030 g/mL (used for diagnostic specific gravity). Convert g/mL to kg/m³ by multiplying by 1,000; to lb/gal by multiplying by 8.345.
