# What is the SI unit of specific heat capacity ?

Specific heat capacity is the quantity of heat needed to raise the temperature per unit mass. The definition of specific heat capacity of any substance is the quantity of heat required to change the temperature of a unit mass of the substance by 1 degree.

$$Specific\, heat\, capacity = \frac{Energy\, required(Q)}{mass(m)\times \Delta T}$$

### SI unit for specific heat

The SI unit for specific heat is joule per kelvin per kilogram (J/K/kg, J/(kg K), J K−1 kg−1, etc.)
