## Gas Mark to Rankine

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 Rankine temperature scale was proposed by William John Macquorn Rankine in 1859 similarly to Kelvin temperature scale. The zero absolute at Rankine scale is also 0 K, and degree of Rankine is the same than Fahrenheit degree. The Rankine is represented as °R after the value, and sometimes like °RA.

The Rankine degree values are calculated from Gas Mark values using the formula $${{126 × GasMark + 3547.35} \over 5}$$
