How to use this calculator
- Enter the mass, the material's specific heat and the temperature change.
- Read the heat energy.
How it works
Heat energy Q = mass × specific heat × temperature change (Q = mcΔT).
Worked example
2 kg water, +30 °C. Q = 2 × 4186 × 30 = 251,160 J.
Common mistakes
- Using the wrong specific heat — water is ~4186 J/kg·°C, but metals are far lower.
- Mixing units — keep mass in kg and specific heat in J/kg·°C.
Frequently asked questions
What's the specific heat of water?
About 4186 J/kg·°C (or 4.186 kJ/kg·°C) — high, which is why water heats and cools slowly.
