Specific Heat Calculator
Solve Q = m c deltaT for heat energy, mass, specific heat, or temperature change. Presets for water, metals, glass, wood, air. Outputs J, kJ, cal, kcal, BTU.
Given mass, specific heat, and temperature change, find Q.
Pick a preset to auto-fill c, or pick Custom to enter your own value.
Mass of the substance. Must be greater than zero.
Auto-filled from the substance preset. Pick Custom to edit.
Final minus initial temperature. K and °C have the same magnitude.
