Understanding Centigrade vs. Celsius
What is Centigrade?
Centigrade was the original name for the temperature scale created by Swedish astronomer Anders Celsius in 1742. The name comes from Latin: "centum" (meaning 100) and "gradus" (meaning steps), referring to the 100-degree interval between the freezing and boiling points of water.
Historical Timeline
- •1742: Anders Celsius creates the centigrade scale
- •1743: Jean-Pierre Christin reverses the scale
- •1948: Scale officially renamed to "Celsius"
- •Today: Both terms are used interchangeably
Why the Name Change?
In 1948, the 9th General Conference on Weights and Measures officially renamed the centigrade scale to "Celsius" in honor of Anders Celsius, the inventor of the temperature scale. This change was made to avoid confusion with other scales and to properly credit the scientist.
