How it's used
Commonly used in everyday life to describe the power consumption of household appliances like light bulbs, heaters, or hair dryers. While the formal term is 瓦, speakers almost exclusively use 火 in casual settings to talk about electrical capacity. It functions as a noun for the unit itself and is often placed directly after the number.
Examples
How many watts does this appliance need to turn on?

Common mistake
Do not confuse this with the literal meaning of fire. In a technical or scientific context, using the formal term 瓦 is preferred over the colloquial 火.
