Rankine to Newton (°R to °N) Converter
1 Rankine equals -89.9562 Newton (1 °R = -89.9562 °N). Convert Rankine to Newton with formula, table, and examples.
To convert Rankine to Newton, use the formula: N = (R - 491.67) x 11/60. The Rankine scale is the absolute Fahrenheit scale used in US thermodynamic engineering, while the Newton scale is Isaac Newton's rarely-used temperature scale. Water freezes at 491.67 degrees R (0 N) and boils at 671.67 degrees R (33 N).
How to Convert Rankine to Newton
- Convert to Kelvin: K = °R * 5 / 9
- Convert to Newton: °N = (K - 273.15) * 33 / 100

Good to Know About Rankine to Newton Conversion
The history of temperature measurement is the history of scientific collaboration and competition across borders. The Rankine scale (used in American aerospace and chemical engineering) and the Newton scale (barely adopted beyond his laboratory) represent different national contributions to solving the same fundamental problem: how to assign numbers to the sensation of hot and cold.
Rankine to Newton: What You Need to Know
The Rankine scale was created by William Rankine, 1859, used in American aerospace and chemical engineering. The Newton scale was created by Isaac Newton, around 1700, barely adopted beyond his laboratory. Converting between them bridges different eras and different measurement philosophies in the history of thermometry.
What is a Rankine? °R
An absolute temperature scale using Fahrenheit-sized degrees. 0 °R equals absolute zero. Used in some US engineering applications, especially thermodynamics.

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.

Rankine to Newton FAQ
-
Use the formula N = (R - 491.67) x 11/60. At the freezing point of water: 491.67 R = 0 N. At the boiling point: 671.67 R = 33 N.
-
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 491.67 R = 0 N. Water boils at 671.67 R = 33 N. These two fixed points anchor both scales and provide easy verification of any conversion calculation.
Non-Frequently Asked Questions About Rankine to Newton
Questions nobody should ask - but someone did.
-
More like translating between two dead languages that were never widely spoken. Rankine is still technically alive in American thermodynamic engineering - think of it as the Latin of temperature scales. Newton's temperature scale is fully extinct - more like Etruscan. Converting between them requires fluency in two obscure measurement traditions that have almost zero overlap in users.
-
A jet engine's combustion temperature of about 1,800 Kelvin (3,240 degrees Rankine) equals approximately 503 degrees Newton. Newton calibrated his scale for laboratory temperatures around human experience. A jet engine at 503 Newton degrees is so far beyond Newton's intended range that the number loses all intuitive meaning.
-
It would solve no problems and create new confusion. Rankine starts at absolute zero and uses Fahrenheit-sized degrees. Newton starts at the freezing point of water and uses degrees roughly 3 times larger than Celsius degrees. Merging them would produce a Frankenstein scale with no natural reference points and no user community. Some things are better left unconsolidated.
