Part of speech: noun

Definitions

2. An electrical unit that signifies one million watts, primarily utilized to quantify the output of power plants
3. A unit measuring power equal to one million watts, commonly used to express large electricity generation capacities

Etymology: "Megawatts" is simply the plural of "megawatt," a compound formed from the prefix "mega-" and "watt." The watt itself is named after James Watt, the Scottish engineer whose improvements to the steam engine made him central to the study of mechanical power, and the SI unit was named in his honour. The prefix "mega-" comes from Ancient Greek "mégas," meaning "great" or "large," which passed into modern scientific use as a standard multiplier meaning one million. Put together, the two parts give a unit that reads literally as "great watt," one million watts. The compound follows the same pattern as other metric-prefixed units, where "mega-" scales the base unit upward. Because the unit describes the output of power plants and the capacity of large electrical systems, it appears most often in discussions of energy production.
