A megawatt (MW) is a unit of power equal to one million watts (W). To convert megawatts to watts, multiply the number of megawatts by 1,000,000. For example, 5 MW equals 5,000,000 W. This conversion is essential in fields like electrical engineering and energy production, where understanding different scales of power measurement is crucial. For instance, large power plants often have capacities measured in megawatts, while household appliances are rated in watts. Accurate conversion between these units ensures proper system design and energy management.
