The SI unit for specific heat capacity is joule per kelvin per kilogram J/kg⋅K, J⋅K ⋅kg . Since an increment of temperature of one 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 J⋅g ⋅K = 1000 J⋅kg ⋅K . The specific heat capacity of a substance (per unit of mass) has dimension L ⋅Θ ⋅T , or (L/T) /Θ.
