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 kingston ontario to london ontario
