Celsius to Delisle

The Celsius or centigrade temperature scale is based on the water tristate, placing the 0 at the point when the liquid water becomes ice, and the 100 at the point when the liquid water becomes gas, both at 1 atm pressure. Its unit is represented with ℃ after the value.

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.

Delisle values are calculated based on the formula $$(100 - Celsius) × {3 \over 2}$$
