How to Convert Rankine to Newton
Temperature conversions like Rankine to Newton use specific non-linear formulas.
Formula:
First convert °R to °C: °C = (°R - 491.67) × 5/9. Then convert °C to °N: °N = °C × 33/100Example Calculation:
Convert 10°R:
1. °C = (10 - 491.67) × 5/9 = -267.59°C
2. °N = -267.59 × 33/100 = -88.31°N

What is a Rankine and a Newton?
The Rankine scale (°R or °Ra) is an absolute thermodynamic temperature scale named after the Scottish engineer and physicist William John Macquorn Rankine. Similar to the Kelvin scale, its zero point is absolute zero, but the degree size is the same as that of the Fahrenheit scale.
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 Rankine 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 Rankine and Newton
The scale was proposed by William Rankine in 1859, shortly after the Kelvin scale was developed. It was created to provide an absolute temperature scale that directly corresponded with the Fahrenheit degrees used widely in engineering at the time.
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.

Common Uses for degrees Rankine
- Engineering (Thermodynamics): Used in some engineering fields, particularly in the United States, where calculations often involve Fahrenheit. It simplifies thermodynamic calculations (like the ideal gas law) when using Imperial units.
- Historical Context: Found in older engineering texts and data.
Common Uses for degrees Newton
- Historical Significance: Primarily of historical interest in the development of thermometry.
- Not used in modern scientific or general applications.
Frequently Asked Questions
Questions About Rankine (°R)
What is absolute zero on the Rankine scale?
Absolute zero is 0 °R, which is equivalent to -459.67 °F or -273.15 °C.
How does Rankine relate to Fahrenheit?
A change of 1 °R is equal to a change of 1 °F. The formula is °R = °F + 459.67.
How does Rankine relate to Kelvin?
The Rankine scale uses Fahrenheit degrees, while Kelvin uses Celsius degrees. Both start at absolute zero. The formula is °R = K × 9/5.
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.
