Celsius and Réaumur Convertor ( °C & °Ré )

Celsius is the temperature scale previously known as the centigrade scale.
The name Centigrade was derived from the Latin - meaning "hundred degrees".
When Anders Celsius - a Swedish astronomer - created his original scale in 1742 he inexplicably chose 0° for the boiling point and 100° for the freezing point.
One year later Frenchman Jean Pierre Cristin proposed an inverted version of the scale - freezing point 0°, boiling point 100°.
He named it Centigrade.
In 1948, by international agreement, Cristin's adapted scale became known as Celsius to honour the Swedish Scientist.
The degree Celsius - symbol: °C - can refer to a specific temperature on the Celsius scale as well as serve as unit increment to indicate a temperature interval.


The Réaumur scale (French pronunciation: ​[ʁeomy(ː)ʁ]; °Ré, °Re, °r), also known as the "octogesimal division", is a temperature scale for which the freezing and boiling points of water are defined as 0 and 80 degrees respectively.
The scale is named for René Antoine Ferchault de Réaumur, who first proposed a similar scale in 1730.
The Réaumur scale was used widely in Europe, particularly in France, Germany and Russia, and was referenced in the works of Dostoyevsky, Flaubert, Tolstoy, and Nabokov.
By the 1790s, France chose the Celsius scale for the metric system instead of the Réaumur measurements, but it was used commonly in some parts of Europe until at least the mid-19th century, and in parts of Russia until the early 20th.
Its main modern uses are in some Italian and Swiss factories for measuring milk temperature during cheese production, and in the Netherlands for measuring temperature when cooking sugar syrup for desserts and sweets.
