- 1瓦數、功率（以瓦特計）；比喻時指「亮眼、耀眼的程度」
Wattage is how much electrical power something uses or produces, counted in watts. A light bulb, a , a speaker, a microwave all have a wattage: "What wattage is that bulb?" "Sixty watts." So wattage is the measurement, and watts are the units — the same relationship as mileage and miles, or voltage and .
In everyday life it comes down to two practical questions. For things that use electricity, high wattage means it eats more power (and costs more to run, and usually gets hotter or brighter). For things that produce it — a speaker, an — high wattage means it can go louder. That is why shop assistants and product boxes talk in wattage.
The word is a little bit technical but not difficult; ordinary people say it without feeling clever. You will often meet it in phrases like "a high-wattage bulb", "low-wattage ", "check the wattage before you plug it in".
English also uses it for star quality: "a high-wattage smile", "an actor of enormous wattage" — meaning shining, , drawing every eye. That use borrows from the light bulb, and it belongs to journalism and reviews, not to normal talk.
組成watt + -age. The -age ending turns a unit into "the amount measured in those units": miles → mileage, volts → voltage, watts → wattage. It came into English from French, which got it from Latin -aticum.
