Editing Specific heat capacity (section)

===International system===
The SI unit for specific heat capacity is joule per kelvin per kilogram {{sfrac|J|kg⋅K}}, J⋅K<sup>−1</sup>⋅kg<sup>−1</sup>.  Since an increment of temperature of one [[Celsius scale|degree Celsius]] is the same as an increment of one kelvin, that is the same as joule per degree Celsius per kilogram: J/(kg⋅°C).  Sometimes the [[gram]] is used instead of kilogram for the unit of mass: 1&nbsp;J⋅g<sup>−1</sup>⋅K<sup>−1</sup> = 1000&nbsp;J⋅kg<sup>−1</sup>⋅K<sup>−1</sup>.

The specific heat capacity of a substance (per unit of mass) has [[dimensional analysis|dimension]] L<sup>2</sup>⋅Θ<sup>−1</sup>⋅T<sup>−2</sup>, or (L/T)<sup>2</sup>/Θ. Therefore, the SI unit J⋅kg<sup>−1</sup>⋅K<sup>−1</sup> is equivalent to [[metre]] squared per [[second]] squared per [[kelvin]] (m<sup>2</sup>⋅K<sup>−1</sup>⋅s<sup>−2</sup>).
