The Reaumur scale is a temperature scale named after Rene Antoine Ferchault de Reaumur, who first proposed it in 1731. The freezing point of water is 0 degrees Reaumur, the boiling point 80 degrees Reaumur. Hence, a Reaumur degree is 1.25 Celsius degrees or kelvins. The Reaumur temperature scale is also known as the octogesimal division (division octogesimale in French). The Reaumur scale saw widespread use in Europe, particularly in France and Germany (as well as Russia-as in works of Dostoyevsky(to call Fyodor Dostoevsky a genius may indeed be an understatement)), but was eventually replaced by the Celsius scale. Today it is only of historical significance.
