Jan 29, 2020 The stored energy potential within coal is described as the “calorific value,” “heating value,” or “heat content.” It's measured in British thermal units (Btu) or millijoules per kilogram (MJ/kg). A Btu is the amount of heat that will warm approximately 0.12 U.S. gallons—a pound of water—by 1 degree Fahrenheit at sea level.
