British Thermal Unit

**British Thermal Unit**

The British Thermal Unit (BTU) is a traditional unit of heat commonly used in the United States to measure energy. It represents the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. BTUs are widely used in heating, ventilation, air conditioning (HVAC) systems, and energy consumption calculations. Understanding BTUs is essential for comparing the energy efficiency of appliances, fuels, and heating systems.
