Important Temperatures In Degrees Celsius

Background and Origin

Named for it's creator Anders Celsius, who proposed it in 1742, the scale was initially defined with the boiling point of water being 0 degrees and the freezing point at 100 degrees. The scale was reversed the following year to match the definition we use today. The revised definition is largely the same definition we use today.

Uses

The vast majority of the world uses the Celsius temperature scale, most of which adopted the use of the scale when they adopted the use of metric units of measure. The United States and a few other countries however still use the Fahrenheit temperature scale.
