BTUs
Heat energy abbreviation
BTUs, or British thermal units, measure heat energy—specifically, the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.
Despite the name, BTUs are used primarily in the United States for rating heating and cooling equipment.
The furnace puts out 80,000 BTUs per hour.
Air conditioners, water heaters, and grills are commonly rated in BTUs, with higher numbers indicating greater heating or cooling capacity.
