Newton to Rømer (°N to °Rø) Converter
1 Newton equals 9.0909 Rømer (1 °N = 9.0909 °Rø). Convert Newton to Rømer with formula, table, and examples.
To convert Newton to Romer, use the formula: Ro = N x 35/22 + 7.5. The Newton scale is Isaac Newton's rarely-used temperature scale, while the Romer scale is the early Danish scale that influenced Fahrenheit. Water freezes at 0 degrees N (7.5 Ro) and boils at 33 degrees N (60 Ro).
How to Convert Newton to Rømer
- Convert to Kelvin: K = °N * 100 / 33 + 273.15
- Convert to Rømer: °Rø = (K - 273.15) * 21 / 40 + 7.5

Good to Know About Newton to Rømer Conversion
The history of temperature measurement is the history of scientific collaboration and competition across borders. The Newton scale (barely adopted beyond his laboratory) and the Romer scale (influenced Fahrenheit) represent different national contributions to solving the same fundamental problem: how to assign numbers to the sensation of hot and cold.
Newton to Rømer: What You Need to Know
The Newton scale was created by Isaac Newton, around 1700, barely adopted beyond his laboratory. The Romer scale was created by Ole Romer, Danish astronomer, around 1701, influenced Fahrenheit. Converting between them bridges different eras and different measurement philosophies in the history of thermometry.
What is a Newton? °N
A temperature scale devised by Isaac Newton around 1700. Water freezes at 0 °N and boils at 33 °N. Not to be confused with the newton unit of force.

A temperature scale proposed by Ole Christensen Rømer in 1701. Water freezes at 7.5 °Rø and boils at 60 °Rø. It influenced Fahrenheit's scale development.

Newton to Rømer FAQ
-
Use the formula Ro = N x 35/22 + 7.5. At the freezing point of water: 0 N = 7.5 Ro. At the boiling point: 33 N = 60 Ro.
-
This conversion is needed when interpreting historical scientific records, comparing temperature data across different measurement traditions, or completing engineering calculations that mix temperature scales from different national standards.
-
Water freezes at 0 N = 7.5 Ro. Water boils at 33 N = 60 Ro. These two fixed points anchor both scales and provide easy verification of any conversion calculation.
Non-Frequently Asked Questions About Newton to Rømer
Questions nobody should ask - but someone did.
-
Almost exactly. Newton created his temperature scale around 1700; Romer created his around 1701. They were working on the same problem at the same time in different countries (England and Denmark). Neither knew about the other's thermometric work, yet both produced scales that would be superseded by Celsius within 50 years.
-
It connects two scales created within a year of each other by two equally prominent scientists in two neighboring European countries, both of which failed to achieve lasting adoption. The symmetry is almost poetic: two brilliant minds, two parallel inventions, two parallel obsolescences. The only asymmetry is that Romer influenced Fahrenheit, giving his scale an indirect legacy that Newton's lacks.
-
A well-educated natural philosopher in 1701 could convert between Newton and Romer degrees if they knew both scales. But since Newton worked in Cambridge and Romer in Copenhagen, with no internet and slow postal service, the chance of anyone in 1701 knowing both scales was essentially zero. The conversion is a modern construction imposed on historical scales that never actually met.
