Specific Heat Calculator

Aug 18, 2022Determine the mass of the sample. We will assume m = 5 kg. Calculate specific heat as c = Q / (mΔT). In our example, it will be equal to c = -63,000 J / (5 kg * -3 K) = 4,200 J/(kg·K). This is the typical heat capacity of water. If you have problems with the units, feel free to use our temperature conversion or weight conversion calculators.
