Celsius vs. Centigrade: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Celsius and Centigrade both refer to the same temperature scale, but "Celsius" is the modern term used internationally since 1948.
Key Differences
Celsius is a temperature scale named after the Swedish astronomer Anders Celsius, who first proposed it in 1742. Centigrade, derived from Latin roots meaning "hundred steps," was the original name of the scale. While the Celsius scale is widely recognized today, the term Centigrade was used earlier to describe the same scale, dividing the temperature range between the freezing and boiling points of water into 100 degrees.

The term Celsius became officially adopted internationally in 1948 to honor Anders Celsius and differentiate the scale from other centigrade scales in use. The Centigrade scale, while essentially the same in measurement, was more commonly used before this change. The transition from Centigrade to Celsius was part of a broader effort in standardizing scientific terminology.

In the Celsius scale, 0 degrees marks the freezing point of water, and 100 degrees its boiling point at standard atmospheric pressure. The Centigrade scale, though named differently, shares these exact reference points. The consistent use of Celsius in scientific and meteorological contexts reflects a global preference for standardized terminology.

While "Celsius" is the term endorsed by international standards organizations like the International System of Units (SI), the term "Centigrade" is still used colloquially in some languages and regions. The practical measurements in both Celsius and Centigrade are identical, with the key difference lying in the nomenclature and historical context.
