Exploring the Legal Definition of British Thermal Unit - Btu
Definition & Meaning
A British thermal unit (Btu) is a measurement of heat energy. Specifically, it is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit, at a temperature of 39.2 degrees Fahrenheit and under standard atmospheric pressure. This unit is commonly used in various fields, including heating, ventilation, and air conditioning (HVAC), as well as in energy production and consumption contexts.
