Celsius
Celsius is a unit of measurement for temperature. It is named after the Swedish astronomer Anders Celsius, who first proposed the Celsius scale in 1742. The Celsius scale is based on the freezing and boiling points of water, with 0 degrees Celsius being the freezing point and 100 degrees Celsius being the boiling point at standard atmospheric pressure.
Conversion
To convert temperatures from Celsius to Fahrenheit, you can use the following formula:
Fahrenheit = (Celsius × 9/5) + 32
And to convert temperatures from Fahrenheit to Celsius, you can use the following formula:
Celsius = (Fahrenheit - 32) × 5/9
