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.
About Rømer
Ole Rømer made significant contributions to the field of temperature measurement.
He was a Danish astronomer known for his work in the late 17th century. The Rømer scale (also known as the Danish scale) was based on the freezing and boiling points of water as many temperature scales are. Rømer's scale used the freezing and boiling reference points as 0 degrees and 60 degrees respectively. While the Rømer scale is no longer used it played a role as an early precursor to the Celsius scale.
