Watt
W
Definition
The watt (W) is the SI derived unit of power, representing the rate of energy transfer or conversion. It is defined as one joule per second and is the standard unit for measuring electrical power, mechanical power, and thermal power in scientific and engineering applications.
History/Origin
The watt was named after James Watt, the Scottish engineer who improved the steam engine. It was adopted as the SI unit of power in 1960, replacing the horsepower as the standard unit for power measurements in the International System of Units.
Current Use
Widely used in electrical engineering, mechanical engineering, and physics for measuring power consumption, generation, and transfer. Essential for calculating energy efficiency, electrical load, and power ratings of devices and systems.
