Celsius (°C)

The Celsius, also known as centigrade, is a unit of temperature difference equal to 1 kelvin (K), originally defined by dividing the interval between the boiling point and freezing point of water into 100 equal divisions. The name "Celsius," after Anders Celsius, officially replaced "centigrade" in 1948. The Celsius scale has largely superceded the Fahrenheit scale.
