Anders Celsius became famous for his recommendation in 1742 to divide the temperature scale of a mercury thermometer at 760mm mercury air pressure into 100 degrees, where 100 is the frozing point and 0 the boiling point of water. Because of the detailed fixation of the measuring circumstances and methods this definition was more exact and enabled a better temperature measurement as with the actual practices, introduced by the glass manufacturer Gabriel Daniel Fahrenheit (1686-1736) and the aristocrate and biologist René-Antoine Ferchault de Réaumur (1683-1757). Later the reversion of the Celsius scale with 0 as the frozing point and 100 as the boiling point of water was introduced, and with this modification it became widely spread....
