Sense: noun/1
Centigrade and Celsius refer to exactly the same temperature scale — both measure temperature with 0° as the freezing point of water and 100° as the boiling point. Celsius is the official name used in science and international standards, named after the Swedish astronomer Anders Celsius. Centigrade (from Latin centum 'hundred' + gradus 'step') was the original everyday term and is still very common in weather reports, cooking, and casual conversation. Fahrenheit is a completely different scale, used mainly in the United States, where water freezes at 32° and boils at 212°. If an American cookbook says 'preheat to 350°' and a British one says 'preheat to 180°', knowing whether the recipe uses Fahrenheit or Centigrade is essential for a successful meal.

Etymology
Centigrade was formed in French in the 1700s by combining Latin centi- (meaning 'hundred') with French grade (meaning 'degree' or 'step'). The name refers to the fact that there are one hundred equal steps — or degrees — between the freezing point and the boiling point of water. The scale is also called Celsius after the Swedish astronomer Anders Celsius, who proposed a similar system in 1742. Although 'Celsius' became the official scientific name in 1948, 'centigrade' remains widely used in everyday English.
