WebThe value 1,300 of something is actually the volumetric specific heat capacity of air, so the right units are k J / m 3 ⋅ ∘ C. The word "volumetric" means that it's computed per unit volume. Divide it by 1.275 kilograms per cubic meters, the density of air, and you will get 1.02 kJ/kg per degree, in agreement with the result two paragraphs above.
