Comparisons among various temperature scales
The Réaumur scale (°Ré, °Re, °R), also known as the octogesimal division, is a temperature scale in which the freezing and boiling points of water are set to 0 and 80 degrees respectively. Kelvin Celsius (Centigrade Fahrenheit Rankine Delisle Newton Réaumur Temperature is a physical property of a system that underlies the common notions of hot and cold something that is hotter generally has the greater temperature The melting point of a solid is the temperature range at which it changes state from solid to Liquid. The boiling point of a liquid is the temperature at which the Vapor pressure of the liquid equals the environmental pressure surrounding the liquid Water is a common Chemical substance that is essential for the survival of all known forms of Life. The scale is named after René Antoine Ferchault de Réaumur, who first proposed it in 1731. "Réaumur" redirects here For other uses see Réaumur (disambiguation. Year 1731 ( MDCCXXXI) was a Common year starting on Monday (link will display the full calendar of the Gregorian calendar (or a Common year
Réaumur’s thermometer was constructed on the principle of taking the freezing point of water as 0°, and graduating the tube into degrees each of which was one-thousandth of the volume contained by the bulb and tube up to the zero mark. It was the dilatability of the particular quality of alcohol employed which made the boiling point of water 80°. In Chemistry, an alcohol is any Organic compound in which a Hydroxyl group ( - O[[hydrogen H]]) is bound to a Carbon Mercurial thermometers, the stems of which are graduated into eighty equal parts between the freezing and boiling points of water, are not Réaumur thermometers in anything but name. Mercury (ˈmɜrkjʊri also called quicksilver or hydrargyrum, is a Chemical element with the symbol Hg ( Latinized hydrargyrum Réaumur may have chosen the octogesimal division because the number 80 could be halved 4 times and still be an integer (40, 20, 10, 5); the number 100, for instance, could only suffer this process twice (50, 25). 80 ( eighty) is the Natural number following 79 and preceding 81. The integers (from the Latin integer, literally "untouched" hence "whole" the word entire comes from the same origin but via French 40 ( forty) is the Natural number following 39 and preceding 41.

For the year 50 CE see 50. 25 ( twenty-five) is the Natural number following 24 and preceding 26.
The Réaumur scale saw widespread use in Europe, particularly in France and Germany as well as Russia, such as in works of Dostoyevsky and Tolstoy.

The Celsius Temperature scale was previously known as the centigrade scale. The metric system is a decimalised system of measurement. It exists in several variations with different choices of base units, though the choice of base units does  Today it is only of historical significance except that it is still used in the measuring of milk temperature in cheese. It is used in some Italian dairies making Parmiggiano-Reggiano and Grana Padano cheeses and in Swiss Alp cheeses.
