How to Convert Rømer to Newton: Step-by-Step Guide
Temperature conversions like Rømer to Newton use specific non-linear formulas.
Formula:
First convert °Rø to °C: °C = (°Rø - 7.5) × 40/21. Then convert °C to °N: °N = °C × 33/100Example Calculation:
Convert 10°Rø:
1. °C = (10 - 7.5) × 40/21 = 4.76°C
2. °N = 4.76 × 33/100 = 1.57°N

The Rømer scale (°Rø) is a historical temperature scale where the freezing point of water is set at 7.5 degrees and the boiling point at 60 degrees.
The Newton scale (°N) is a temperature scale devised by Isaac Newton around 1700. It sets the freezing point of water at 0 degrees Newton and the boiling point at 33 degrees Newton.
Note: The Rømer is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Newton belongs to the imperial/US customary system.
History of the Rømer and Newton
Invented by the Danish astronomer Ole Christensen Rømer in 1701. Rømer based his scale on two points: the freezing point of brine (0 °Rø) and the boiling point of water (60 °Rø). He later observed pure water froze at 7.5 °Rø. Daniel Fahrenheit visited Rømer and reportedly based his own scale on Rømer's work, multiplying the number of degrees by four.
Newton developed his scale for practical use, calling it the "thermometric degree." He defined it based on the freezing point of water (0 °N) and body temperature (around 12 °N). He later extrapolated it to the boiling point of water (33 °N). It was one of the precursors to the Celsius scale.

Additional Unit Information
About Rømer (°Rø)
What are the freezing and boiling points of water in Rømer?
Water freezes at 7.5 °Rø and boils at 60 °Rø.
How did Rømer influence Fahrenheit?
Fahrenheit adopted Rømer's use of two reference points and expanded the scale, likely multiplying Rømer's degrees by 4 to avoid fractions and negative numbers for everyday temperatures.
How does Rømer relate to Celsius?
The relationship is °Rø = °C × 21/40 + 7.5.
About Newton (°N)
What are the freezing and boiling points of water in Newton?
Water freezes at 0 °N and boils at 33 °N.
How does the Newton scale relate to Celsius?
The Newton degree is much larger than the Celsius degree. The formula is °N = °C × 33/100.
Did Newton use mercury thermometers?
Newton didn't use mercury; his early work involved linseed oil thermometers. The scale defines temperature points rather than the substance used in the thermometer.
