How to Use This Calculator
  1. Enter the mass of substance in grams and its specific heat capacity (J/g·°C).
  2. Set the temperature change (ΔT) in °C.
  3. Optionally enter moles of substance for molar heat calculations.
  4. Review Heat (q) in joules, kilojoules, calories, and kilocalories.

What each input means

Mass
Mass of the substance being heated or cooled in grams
Specific Heat Capacity
Specific heat capacity of the substance (water = 4.184 J/(g·K))
Temperature Change (ΔT)
Change in temperature (final minus initial). Negative = cooling, positive = heating
Moles (optional)
Moles of reactant — used to calculate molar enthalpy. Leave 0 to skip.

How this is calculated

Formula

q = m × c × ΔT
