About BTU per Pound (BTU/lb)
An imperial specific-energy unit dominant in US steam tables, HVAC enthalpy calculations, and heating-fuel energy content. Natural gas heating value is often quoted in BTU/lb or BTU/scf. Refrigerant enthalpy/entropy tables in US-edition reference handbooks use BTU/lb throughout. 1 BTU/lb = 2.326 kJ/kg.
About Kilojoule per Kilogram (kJ/kg)
A metric specific-energy unit equal to 1,000 J/kg. kJ/kg is the dominant unit in thermodynamics — specific enthalpy and specific internal energy values in steam tables and refrigerant tables are quoted in kJ/kg. Saturated water enthalpy at 100°C: ~419 kJ/kg; saturated steam at 100°C: ~2,676 kJ/kg. Food energy content outside the US is also reported in kJ/kg.
