Celsius

The Celsius scale is a temperature scale used in most countries around the world. It is named after the Swedish astronomer Anders Celsius, who first proposed it in 1742. The Celsius scale is based on the freezing point of water at 0 degrees and the boiling point of water at 100 degrees, under standard atmospheric pressure.

Converting between Celsius and Fahrenheit

To convert a temperature from Celsius to Fahrenheit, you can use the following formula:

Fahrenheit = (Celsius × 9/5) + 32

Conversely, to convert a temperature from Fahrenheit to Celsius, you can use the following formula:

Celsius = (Fahrenheit - 32) × 5/9
