Newton (°N) - Unit Information & Conversion
What is a Newton?
Definition
The Newton scale (°N) is a temperature scale devised by Isaac Newton around 1700. It sets the freezing point of water at 0 degrees Newton and the boiling point at 33 degrees Newton.
History
Newton developed his scale for practical use, calling it the "thermometric degree." He defined it based on the freezing point of water (0 °N) and body temperature (around 12 °N). He later extrapolated it to the boiling point of water (33 °N). It was one of the precursors to the Celsius scale.
Common Uses
- Historical Significance: Primarily of historical interest in the development of thermometry.
- Not used in modern scientific or general applications.
Unit FAQs
What are the freezing and boiling points of water in Newton?
Water freezes at 0 °N and boils at 33 °N.
How does the Newton scale relate to Celsius?
The Newton degree is much larger than the Celsius degree. The formula is °N = °C × 33/100.
Did Newton use mercury thermometers?
Newton didn't use mercury; his early work involved linseed oil thermometers. The scale defines temperature points rather than the substance used in the thermometer.
