The specific heat capacity of a substance, chemical compound, or molecule, is a measure of the amount of heat energy necessary to increase the temperature of a unit quantity of that substance by a given temperature interval.
Specific Heat Conversion Factors
1kj/ (kg × oC) = .23885 Btu/(lbm × oF)
Q is taken to be the heat energy put into a certain amount of a substance with mass m,
c is the specific heat of the substance, and
ΔT is the temperature change.
Water, for example, has a specific heat capacity of 4.186 joules/gram oC. In other words, in order to increase the temperature of one gram of liquid water by one degree celsius, you will have to add introduce 4.186 joules of heat energy into the system. The symbol for specific heat is denoted as c or sometimes C, depending on how the substance is measured. The SI units for specific heat are J/ (kg.K).
Convert the 25 BTU/pound oF to various other units.
Calorie/gram oC = 25
Kilojoule/kilogram oK = 104.67000000021733
