The SI unit for heat capacity of an object is joule per kelvin (J/K or J⋅K ). Since an increment of temperature of one degree Celsius is the same as an increment of one kelvin, that is the same unit as J/°C. The heat capacity of an object is an amount of energy divided by a temperature change, which has the dimension L ⋅M⋅T ⋅Θ . Therefore, the SI unit J/K is equivalent to kilogram meter squared per Webb28 dec. 2024 · The SI unit of heat is the joule, where 1 joule = 1 newton × meter.
