Web1 cal = 4.187 J (International Steam Table calorie) An equivalent definition is used in the British system, still widely used especially in the United States: the British thermal unit or BTU represents the amount of heat required to raise by one Fahrenheit degree the temperature of 1 lb (pound) of water (0.4535924 kg). WebMar 13, 2024 · For the low-pressure steam typically used in heating systems, that ratio is 1,194 BTUs for every pound of steam the system provides. If your boiler supplies 400 pounds of steam per hour, for example, you would multiply 400 pounds by 1,194 to arrive at a figure of 477,600 BTUs.
