Power is measured in units called watts. The watt (W) is defined as one joule per second and is a standard unit used to quantify the rate of energy transfer or conversion.
To explain further, power essentially indicates how quickly work is done or energy is used. For example, if a light bulb consumes 60 watts, it means that it uses 60 joules of energy every second. Various applications of power measurement include electricity consumption, mechanical power, and thermal power.
Additionally, other units can also represent power, such as horsepower (commonly used in engines) and kilowatts (often used for larger energy applications), but the watt remains the most universally recognized unit.
