Specific Heat Calculator

Specific heat capacity is the amount of thermal energy required to raise the temperature of 1 kg of a substance by 1 kelvin. It is a characteristic property of each material, expressed in J/(kg·K).

The calculator uses Q = m · c · ΔT, where Q is thermal energy in joules, m is mass in kilograms, c is specific heat capacity in J/(kg·K), and ΔT is temperature change in kelvins.

Water has a specific heat capacity of approximately 4186 J/(kg·K), which is exceptionally high and makes water an excellent thermal medium.

Yes — only the temperature difference ΔT matters in the formula. A change of 1°C equals a change of 1 K, so you can use either scale for the difference.

A negative Q means the substance is releasing heat — cooling down. You get a negative result by entering a negative ΔT value.

Water (4186 J/(kg·K)) and ice (2090 J/(kg·K)) are high. Common metals are much lower: copper ≈ 385, iron ≈ 449, aluminium ≈ 897 J/(kg·K).

1 kcal = 4184 J. Divide the value in joules by 4184 to get kilocalories. The dietary calorie (kcal) is widely used in nutrition and food energy assessment.

Results are mathematically accurate for the entered data. Real specific heat values may vary with temperature, pressure, and material purity.

In building heating systems, heat exchanger design, food technology, materials engineering, laboratory calorimetry, and physics education.

Yes, values can vary slightly. Tabulated values are averages. For precise engineering work, consult thermodynamic tables for the relevant temperature range.
