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.
About Grams per cubic centimetre
The gram per cubic centimetre (g/cm³) equals 1000 kg/m³, the most intuitive density unit in material science and chemistry. It equals 1 kg/L and 1 t/m³. Pure water at 4°C is 0.9998 g/cm³; aluminium 2.70 g/cm³; iron 7.87 g/cm³; gold 19.30 g/cm³; osmium 22.59 g/cm³. Polymer datasheets, mineralogy, and gemological tables routinely use g/cm³. 1 g/cm³ = 1000 kg/m³ ≈62.428 lb/ft³.
