## Réaumur to Gas Mark

The Réaumur temperature scale was proposed by René Antoine Ferchault de Réaumur in 1730, and it is based on the water tristate as well as Celsius, placing the 0 at the point when the liquid water freezes, and the value of 80 at the point when the liquid water boils. Its unit is represented with °Ré, with °Re, and sometimes with °r after the value.

As the wikipedia starts saying, the Gas Mark temperature scale is used on gas ovens and cookers in the United Kingdom, Ireland and some Commonwealth of Nations countries introduced by L. Chatterton's book Modern Cookery in 1943. The unit is represented by the capital letter G after the value, fixing the degree of 1 G at 275 ℉, and each increment is equivalent to 25 ℉.

The Gas Mark temperature scale values are calculated from Réaumur using the formula $${{5 × Réaumur - 484} \over 56}$$
