What are Watt and Btu

Definition of Watt

A watt, named after James Watt, is the International System of Units (SI) derived unit of power. It quantifies the rate of energy transfer equivalent to one joule per second. This measurement is critical in various fields such as electrical engineering and physics, offering a standardized method to express power consumption or output. The watt serves as a cornerstone in the understanding of energy dynamics, facilitating the comparison and calculation of power in appliances, engines, and other systems. Its widespread use ensures consistency and clarity in energy-related discussions and analyses.

Definition of Btu

The British Thermal Unit (Btu) is a traditional unit of heat. It represents the amount of heat required to increase the temperature of one pound of water by one degree Fahrenheit. Although not part of the International System of Units, the Btu is commonly used in the power, steam generation, heating, and air conditioning industries. It helps quantify the energy content of fuels and the efficiency of heating and cooling systems. The Btu remains a crucial unit in the energy sector, bridging the gap between practical energy consumption and theoretical energy calculations.
