Definition:Celsius

Definition
Celsius is a temperature scale.

Its two reference points are:
 * $0 \cels$, which is set at the melting point of water.
 * $100 \cels$, which is set at the boiling point of water, as defined at sea level and standard atmospheric pressure.

A temperature measured in Celsius is often referred to as so many degrees Celsius.
