Delisle to Celsius

Delisle (°De): The Delisle scale is an obsolete temperature scale invented in 1732. It is unusual because it is an inverted scale, where the boiling point of water (0 °De) is lower than the freezing point (150 °De).

Celsius (°C): The Celsius scale, also known as the centigrade scale, is the most widely used temperature scale in the world. It is an interval system defined by 0 °C as the freezing point of water and 100 °C as the boiling point of water at standard atmospheric pressure.
