- 1n/wɑːt/瓦特／瓦
A unit for measuring electric power, often shown on light bulbs and machines.
「watt」是量「電的力量有多大」的單位，中文叫「瓦」。可以想成它在數「這個東西一秒鐘用掉多少電」——數字越大，電燈越亮、機器越有力。燈泡上寫 60W 就是 60 瓦，看到 W 這個字母就是它的縮寫。

core核心畫面
You can think of a watt as the unit that tells you how hard a machine is working — how fast it uses up electric power. A bigger number means more light, more heat, more push.
From the word’s history
Named after James Watt, the Scottish engineer who improved the steam engine; the unit of power was named in his honour.
這個單位是用蘇格蘭工程師詹姆斯·瓦特（James Watt）的名字命名的，他大幅改良了蒸汽機，後人為了紀念他，就把功率（電力）的單位叫做 watt。所以這個字本身來自一個人名，不是從某個畫面延伸出來的。
