Detailed explanation-1: -Celsius, also called centigrade, scale based on 0° for the freezing point of water and 100° for the boiling point of water. Invented in 1742 by the Swedish astronomer Anders Celsius, it is sometimes called the centigrade scale because of the 100-degree interval between the defined points.
Detailed explanation-2: -The interval between the ice point and the steam point is divided into 100 equal divisions. Each such division is called one degree Celsius and denoted by °C.
Detailed explanation-3: -It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a variant of it in 1742. Before being renamed in 1948 to honour Celsius, the unit was called centigrade, from the Latin centum, which means 100, and gradus, which means steps.
Detailed explanation-4: -The Celsius scale was created by Anders Celsius, who was a Swedish astronomer. Originally, Anders set 0°C to be the boiling point of water, and 100°C to be the freezing point!
