Specific Heat Calculator
Calculate heat energy using Q = mcΔT. Enter mass, specific heat capacity, and temperature change.
How to Use the Specific Heat Calculator
- Enter the mass of the substance in kilograms.
- Enter the specific heat capacity in J/(kg·K) (water = 4184).
- Enter the temperature change in °C or K.

| Water: c = 4,184 J/(kg·K) | 1 kg × 1 °C = 4,184 J |
| Iron: c = 449 J/(kg·K) | 1 kg × 1 °C = 449 J |
| Aluminum: c = 897 J/(kg·K) | 1 kg × 1 °C = 897 J |
| Copper: c = 385 J/(kg·K) | 1 kg × 1 °C = 385 J |
| Air: c = 1,005 J/(kg·K) | 1 kg × 1 °C = 1,005 J |

الصيغة
Q = m × c × ΔT, where Q is heat (J), m is mass (kg), c is specific heat capacity (J/(kg·K)), ΔT is temperature change (K or °C).
الأسئلة الشائعة
What is specific heat capacity?
It is the amount of heat needed to raise 1 kg of a substance by 1 °C. Water has c = 4,184 J/(kg·K).
Are °C and K interchangeable for ΔT?
Yes, a change of 1 °C equals a change of 1 K, so both work for ΔT.
Is this calculator free?
Yes, all OhMyCalc calculators are completely free.
