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 Calorie per Gram (cal/g)
A CGS specific-energy unit numerically identical to kcal/kg (= 4.184 kJ/kg). Used in chemistry for reaction enthalpies per unit mass, food science for nutritional energy, and legacy thermochemistry literature. Food labels outside the US that show kcal/100g are effectively displaying this unit scaled down.
