## Newton scale to Gas Mark

The Newton temperature scale was defined by Isaac Newton in 1701 setting as 0 on this scale "the heat of air in winter at which water begins to freeze", or in other words, 0 as in Celsius scale, and the value 33 for "heat at which water begins to boil", so around 100 ℃, being exactly 100 the value commonly used for conversions between both scales. The Newton is represented as °N 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 scale degree values are calculated based on the formula $${{100 × Newton - 3993} \over 462}$$
