Specific Heat Calculator

Your details

Pick a preset to auto-fill its specific heat in J/(kg·K), or choose Custom to type your own value.
Mass of the substance being heated or cooled.
Auto-filled from the substance preset. Choose Custom to override it.
On: enter a starting and ending temperature. Off: enter the change ΔT directly.
Final temperature minus initial temperature. A 1 °C change equals a 1 K change.

The quantity you chose to solve for, in your selected display units.

Result (SI base unit)20,930

The heat energy is 20,930 J.

  • Q = m·c·ΔT: the heat needed scales with how much mass you have, the material, and the size of the temperature change.
  • Specific heat c is the energy to raise 1 kg by 1 K; water’s high 4186 J/(kg·K) is why it warms and cools slowly.
  • A positive Q (and ΔT) means heat is added; a negative value means heat is removed and the substance cools.

Next stepSwitch the "Solve for" selector to back-check your answer, or change the substance to compare materials.
