Unit BTU
Name British thermal unit
Category Energy
Details In the field of energy, the British Thermal Unit (BTU) is a traditional unit of heat or thermal energy. It is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit (1°F). BTUs are commonly used to quantify the energy content of various fuels, including natural gas, coal, and oil. These measurements can be used to determine the efficiency of energy conversion processes, such as those found in heating and cooling systems or power plants, as well as to compare the energy content of different fuels.

BTU is also often used in the United States to express the heat output of heating, ventilation, and air conditioning (HVAC) equipment, such as furnaces and air conditioners, as well as heat losses and gains in buildings. This allows for the comparison and selection of appropriate HVAC equipment based on the specific energy requirements of a space.

It's important to note that the BTU is not part of the International System of Units (SI), which is the modern, globally recognized set of units for scientific measurements. In SI, energy is typically measured in joules (J), and 1 BTU is approximately equal to 1,055 joules.
