Delisle to Newton

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).

Newton (°N): The Newton scale was devised by Isaac Newton around 1700. It used the freezing point of water as 0 and the boiling point as 33. It is considered a direct predecessor to the Celsius scale.
