The calculator below can be used to calculate the liquid water specific heat at constant volume or constant pressure and given temperatures.
The output specific heat is given as kJ/(kmol*K), kJ/(kg*K), kWh/(kg*K), kcal/(kg K), Btu(IT)/(mol*°R) and Btu(IT)/(lb m *°R)
Note! Temperature must be within the ranges 0-370 °C, 32-700 °F, 273-645 K and 492-1160 °R to get valid values.
Choose the actual unit of temperature:
