What units are used for specific heat capacity?

Specific heat capacity tells us how much energy is needed to raise the temperature of a certain mass by a certain amount. Since it’s energy per unit mass per unit temperature, the unit is joules per kilogram per degree Celsius, written as J/(kg·°C). Sometimes you’ll see J/(kg·K) because a change of 1 degree Celsius equals a change of 1 kelvin. The other options don’t fit because they miss either the mass factor or the temperature change, or they describe a different property altogether.
