How many?

Degrees Roemer

The Rømer scale, also known as Romer or Roemer, is a temperature scale named after the Danish astronomer Ole Christensen Rømer, who proposed it in 1701. It is based on the freezing point of pure water being 7.5 degrees and the boiling point of water as 60 degrees. This scale was the first commonly used temperature scale and was used by Fahrenheit when he started his scale, until he discovered a colder cold.

Degrees Newton

The Newton scale is a temperature scale devised by Isaac Newton in 1701. He called his device a 'thermometer', but he did not use the term 'temperature', speaking of 'degrees of heat' instead. Newton's publication represents the first attempt to introduce an objective way of measuring (what would come to be called) temperature. Invented by Sir Isaac Newton, it predates the more well known degrees Celsius and Fahrenheit as he likely needed a form of tempereature measurement for his experiements.
