A megawatt is a million watts. A watt is a small unit of power — how much energy something uses or makes at one moment — so a megawatt is the size you use for a power station, a big wind farm, or a factory, not a lamp. A hair dryer might use about a thousand watts (one kilowatt); a megawatt is a thousand times that.

A megawatt is a million watts一megawatt是一百萬瓦 A watt is a small unit of powerwatt是一個很小的功率單位 how much energy something uses or makes at one moment也就是某個東西在某一瞬間所使用或產生的能量多寡 so a megawatt is the size you use for a power station, a big wind farm, or a factory所以megawatt是用在發電廠、大型風力發電場、或工廠這種規模的單位 not a lamp不是用在一盞燈上 A hair dryer might use about a thousand watts (one kilowatt)吹風機大概會用到一千瓦（也就是一個kilowatt） a megawatt is a thousand times thatmegawatt是那個的一千倍

Electricity companies, engineers, and news about energy use the word. There is also an adjective use: a megawatt plant, meaning it runs at that power.

Electricity companies, engineers, and news about energy use the word電力公司、工程師、和能源相關的新聞都會用這個字 There is also an adjective use這個字也有形容詞用法 a megawatt plant像是a megawatt plant（百萬瓦等級的電廠） meaning it runs at that power意思是它是以那樣的功率在運轉

Though actually people often mix watts (power right now) with watt-hours (energy over time). A megawatt-hour is a different, related idea: power times hours.

Though actually people often mix watts (power right now) with watt-hours (energy over time)不過大家其實常常把watts（當下的功率）和watt-hours（一段時間累積的能量）搞混 A megawatt-hour is a different, related ideamegawatt-hour是另一個相關但不同的概念 power times hours也就是功率乘以小時數

For learners, lock megawatt to a million watts of power.

For learners, lock megawatt to a million watts of power對學習者來說，就把megawatt牢牢記成「一百萬瓦的功率」就好
