0.55556 kelvins
= -272.59 °C= -458.67 °F
equals 0.55556 kelvinsFormula: K = °R × 5/9
Degree Rankine to Kelvin formula
K = °R × 5/9
Convert 5 degrees Rankine to kelvins
- Start with 5 degrees Rankine.
- Multiply by the conversion factor: 5 × 0.555556 = 2.7778.
- So 5 °R = 2.7778 K.

Unit definitions
What is a degree Rankine?
The degree Rankine is an absolute temperature scale whose zero is absolute zero but whose degree size matches Fahrenheit. It is used in some United States engineering fields, especially thermodynamics and combustion. Water freezes at about 491.67 °R.
What is a kelvin?
The kelvin is the SI base unit of thermodynamic temperature, redefined in 2019 via the Boltzmann constant. Its zero point is absolute zero, the coldest possible temperature, and it uses the same degree size as Celsius. It is standard in science and engineering.
Frequently asked questions
How many kelvins are in one degree Rankine?
One degree Rankine equals 0.55556 kelvins (1 °R = 0.55556 K).
How do I convert degrees Rankine to kelvins?
Multiply the value in degrees Rankine by 0.555556. For example, 10 °R × 0.555556 = 5.5556 K.
Which is bigger — a degree Rankine or a kelvin?
