The British Thermal Unit (BTU) is a unit of energy used in the United States to measure heating and cooling capacities. It represents the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. BTUs are commonly used in the HVAC industry to determine the size and efficiency of heating and cooling systems.
The metric unit is the calorie, which is the amount of heat needed to increase the temperature of a gram of pure water one degree Celsius. The standard unit is the British Thermal Unit (BTU), which is the amount of heat needed to raise the temperature of a pound of pure water one degree Fahrenheit.
