How to convert kelvins to degrees Réaumur
°Ré = (K − 273.15) × 4/5Temperature scales have different zero points, so the conversion needs an offset as well as a scale factor. In one step: °Ré = K × 0.8 − 218.52.
Worked examples
- 0 kelvins(0 − 273.15) × 4/5 = −218.52 °Ré
- 273.15 kelvins(273.15 − 273.15) × 4/5 = 0 °Ré
- 300 kelvins(300 − 273.15) × 4/5 = 21.48 °Ré
- 373.15 kelvins(373.15 − 273.15) × 4/5 = 80 °Ré
- 1,000 kelvins(1,000 − 273.15) × 4/5 = 581.48 °Ré

About the units
Kelvin (K)
The SI base unit of thermodynamic temperature, defined by fixing the Boltzmann constant. 0 K is absolute zero; a kelvin is the same size as a Celsius degree.
Degree Réaumur (°Ré)
A historical scale with water freezing at 0 °Ré and boiling at 80 °Ré.
Frequently asked questions
What is the formula to convert kelvins to degrees Réaumur?
°Ré = (K − 273.15) × 4/5. Temperature scales have different zero points, so the conversion needs an offset as well as a scale factor. In one step: °Ré = K × 0.8 − 218.52.
What is 273.15 kelvins in degrees Réaumur?
273.15 K = 0 °Ré.
What is 0 K in °Ré?
0 K = −218.52 °Ré.
Can I just multiply to convert kelvins to degrees Réaumur?
No. K and °Ré have different zero points, so a single multiplication gives the wrong answer. Use the full formula above, or the converter. To convert a temperature difference (such as a 10-degree rise), use the temperature interval converter instead.
Is this K to °Ré converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
