How to use this tool

  1. Enter mass, specific heat capacity and temperature change δt in the fields above.
  2. Results update instantly as you type — or click Calculate.
  3. Read your heat energy q and the full breakdown beneath it.

The human body's average specific heat is roughly 3 470 J/kg·K, meaning a 1°C fever represents a significant stored energy change.

Frequently asked questions

What are common specific heat values?
Water: 4186 J/kg·K (very high — why it's used as a coolant), iron: 450, aluminium: 900, copper: 385, ethanol: 2440 J/kg·K.
Is ΔT in Celsius or Kelvin?
Either, since a change of 1 °C equals a change of 1 K. Always use the magnitude of the change.
