About the Fahrenheit scale
Fahrenheit is a relative temperature scale created by the Polish-German physicist Daniel Gabriel Fahrenheit. It is mainly used in the United States and is less common in science compared to the Celsius (or Centigrade) scale.
Fahrenheit is based on the freezing and boiling points of water at standard atmospheric pressure with 32°F at freezing point and 212°F at boiling point.
Whilst Fahrenheit is still commonly used in the United States it is important to note that most of the world relies on Celsius.
About Newton (temperature scale)
The Newton scale is a temperature scale that is now obsolete.
On the Newton scale the zero point is the freezing point of water and 33 degrees is the boiling point. This means that each degree on the Newton scale is significantly larger than a degree on the Celsius or Fahrenheit scales.
The Newton scale has been consigned to the history books but may be referenced in some (very) old textbooks.
