## Rankine to Delisle

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 Delisle temperature scale was defined by Joseph-Nicolas Delisle in 1732. This measure adjust 0 at the point of the boiling water and 150 as the freezing point of the water. The unit is represented by °D (and sometimes as °De) after the value.

The Delisle values are calculated from Rankine values using the formula $$(671.67 - Rankine) × {5 \over 6}$$
