Formula
The Specific Heat Calculator uses the formula:
Heat energy = Mass × Specific heat capacity × Temperature change
Worked example
For example, with mass of 100 g, specific heat capacity of 4.18 J/g·°C and temperature change of 20 °C, the heat energy is 8,360.0.
| Mass | 100 g |
|---|---|
| Specific heat capacity | 4.18 J/g·°C |
| Temperature change | 20 °C |
| Heat energy | 8,360.0 |

Frequently asked questions
Use Q = m × c × ΔT. Heating 100 g of water (c = 4.18) by 20°C takes 100 × 4.18 × 20 = 8,360 joules.
It is the energy needed to raise 1 gram of a substance by 1°C. Water's high value (4.18 J/g·°C) makes it slow to heat and cool.
ΔT is the change in temperature — the final temperature minus the starting temperature.
Yes. A negative ΔT means cooling, so Q is negative, representing heat released rather than absorbed.
