1.8 degrees Rankine
= -272.15 °C= -457.87 °F
equals 1.8 degrees RankineFormula: °R = K × 9/5
Kelvin to Degree Rankine formula
°R = K × 9/5
Convert 5 kelvins to degrees Rankine
- Start with 5 kelvins.
- Multiply by the conversion factor: 5 × 1.8 = 9.
- So 5 K = 9 °R.

Unit definitions
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.
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.
Frequently asked questions
How many degrees Rankine are in one kelvin?
One kelvin equals 1.8 degrees Rankine (1 K = 1.8 °R).
How do I convert kelvins to degrees Rankine?
Multiply the value in kelvins by 1.8. For example, 10 K × 1.8 = 18 °R.
Which is bigger — a kelvin or a degree Rankine?
A kelvin is bigger: one kelvin contains 1.8 degrees Rankine.
