About Newton

Newton (°N) was devised by Isaac Newton around 1700 and published anonymously in 1701. The scale places water's freezing point at 0°N and boiling point at 33°N - a choice that allowed body temperature to fall at approximately 12°N. Newton used linseed oil as the thermometric fluid and described his scale in the Philosophical Transactions of the Royal Society. Although never widely adopted, it is historically significant as one of the earliest systematic temperature scales and directly inspired Ole Rømer, who visited Newton, and later Daniel Gabriel Fahrenheit, who built upon Rømer's work.

About Rømer

Rømer (°Rø) was designed by Danish astronomer Ole Christensen Rømer in 1701, making it one of the earliest calibrated temperature scales using two fixed points. It sets water's freezing point at 7.5°Rø and boiling point at 60°Rø; the offset of 7.5 at freezing was chosen to avoid negative numbers during the coldest Danish winters. In 1708, Daniel Gabriel Fahrenheit visited Rømer and was directly inspired by his thermometer design to create the Fahrenheit scale. Body temperature on the Rømer scale is approximately 22.5°Rø. Though now obsolete, Rømer's scale holds an important place in thermometric history.
