Sensible Heat Transfer Calculator
Estimate sensible heat absorbed or released by a material when its temperature changes, using mass and specific heat capacity. An optional duration gives an average heat-transfer rate.
How to use this calculator
- Enter mass, specific heat capacity and signed temperature change. Optionally add a positive duration in seconds to estimate average power.
- Check the labels and units before applying the result to a real task.
- Change one input at a time when comparing scenarios.
Formula and method
Q = mcΔT; average power = Q/Δt
- Q = mcΔT; average power = Q/Δt
- The model assumes constant specific heat and excludes phase changes, environmental heat loss and temperature gradients.
Worked examples
Worked example
Heat 2 kg of water by 15°C using c = 4,186 J/(kg·°C).
Q = 2×4,186×15 = 125,580 J.
Q = 2×4,186×15 = 125,580 J.
Understanding the result

Frequently asked questions
What does negative heat transfer mean?
A negative temperature change gives a negative Q under this convention, meaning the material releases sensible heat.
What specific heat value should I use?
Use a material reference suitable for the temperature range. Specific heat can vary with temperature and material composition.
Does Q include melting or boiling?
No. Phase changes require latent heat terms and cannot be represented by this sensible-heat equation alone.
