About Cubic metres per kilogram
The cubic metre per kilogram (m³/kg) is the SI coherent derived unit of specific volume - the reciprocal of density. In steam and refrigerant thermodynamics, m³/kg appears in state tables: water at 100°C, 0.1 MPa has specific volume 1.674 m³/kg (vapour) and 1.044 × 10⁻³ m³/kg (liquid). The specific gas constant and molar volume calculations use m³/kg. 1 m³/kg = 1000 L/kg = 1000 cm³/g.
About Cubic metres per gram
The cubic metre per gram (m³/g) equals 1000 m³/kg, used for ultra-low-density media. Highly porous aerogels achieve apparent specific volumes of 0.5-10 m³/g; bulk activated-carbon specific volumes reach 1-3 m³/g per BET surface measurements. Atmospheric aerosol specific volume and trace-gas concentration calculations also employ m³/g. 1 m³/g = 1000 m³/kg = 10⁶ cm³/g.
