Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Constant heat capacity, no phase transition or losses. A signed temperature change gives signed heat absorbed.
Example Calculation
- Mass: 2 kg
- Specific heat: 1000 J/(kg·K)
- Temperature change: 20 K
Mass = 2; Specific heat = 1000; Temperature change = 20. Primary result: 40000.
Frequently asked questions
How do I use this calculator?
Enter mass, specific heat, temperature change. The result updates automatically. Use Reset to restore the example values.
What method does it use?
Q=mass ×specific heat ×temperature change.. Constant heat capacity, no phase transition or losses. A signed temperature change gives signed heat absorbed.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
