AI overview
A watt is the standard unit used to measure power—the rate at which energy is being used or transferred—and is equal to one joule of energy per second. It matters because it's the universal way we quantify how much energy devices consume or produce, from light bulbs to power plants, making it essential for understanding and managing energy use.
