Formula Used
Main equation: Q = m × c × ΔT
Specific heat: c = Q / (m × ΔT)
Heat transfer: Q = m × c × ΔT
Mass: m = Q / (c × ΔT)
Temperature change: ΔT = Q / (m × c)
The calculator first converts all inputs to base units: joules, kilograms, and kelvin difference. It then solves the selected unknown and reports equivalent values in several common units.

FAQs
1. What does specific heat mean for a solid?
Specific heat is the energy needed to raise one kilogram of a solid by one kelvin or degree Celsius. Higher values mean the material needs more heat to warm up.
2. Why are kelvin and Celsius differences treated the same?
A temperature interval of 1 K equals a temperature interval of 1 °C. Only absolute temperature origins differ, so ΔT conversions between those two scales are identical.
3. Can I use this for cooling as well as heating?
Yes. Negative heat or negative temperature change represents cooling. The calculator preserves signs, helping you see whether energy entered or left the solid.
4. Should I enter mass in grams or kilograms?
Either works. The calculator converts grams, kilograms, and pounds into a common base unit before solving, so the final physics remains consistent.
5. When should I use a material preset?
Use a preset when you know the material but not its specific heat. It speeds up estimation, classroom demonstrations, and quick engineering checks.
6. Why might I get a negative mass or specific heat?
That usually means the signs of heat and temperature change disagree with each other. Check whether the process describes heating or cooling and verify your input direction.
7. Does this calculator include phase changes?
No. It assumes the solid stays in the same phase. Melting, freezing, or other phase changes require latent heat terms and a different model.
8. What does the graph show?
The graph shows how heat transfer changes with temperature rise for the solved mass and specific heat. The steeper the line, the more energy each degree requires.
