Celsius is a word that is used to measure temperature. It is named after a scientist named Anders Celsius. In most countries outside of the United States, temperatures are measured in Celsius. If you want to talk about the temperature in a way that people from other countries will understand, you should use Celsius. For example, if it's 20 degrees Celsius outside, that means it is a nice day, but if it's 0 degrees Celsius outside, it is very cold.
