- 1千瓦（kW）
A kilowatt is a unit for measuring electrical power: how hard electricity is working at one moment. One kilowatt is 1,000 watts. A small heater or a microwave might use around one or two kilowatts while it is on. The short form is kW. This kilo- is the ordinary 1,000, not 1,024. Though actually, the number on an electricity bill is usually not kilowatts but kilowatt-hours. A kilowatt tells you how strong the flow is right now; a kilowatt-hour tells you how much energy you used over time, which is what you pay for. People mix those two up all the time, even in English-speaking countries. The watt in the word is named after James Watt. You will meet kilowatts on labels, generators, and solar panels, not as a measure of computer files.
組成kilo- (“thousand”) + watt (the unit of power).
