Newton to Celsius

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.

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.
