The molar heat capacity of a substance has the same dimension as the heat capacity of an object; namely, L ⋅M⋅T ⋅Θ, or M(L/T) /Θ. (Indeed, it is the heat capacity of the object that consists of an Avogadro number of molecules of the substance.) Therefore, the SI unit J⋅K ⋅mol is equivalent to kilogram metre squared per second squared per kelvin (kg⋅m ⋅K ⋅s).
