Convert Kelvin to Réaumur
Kelvin to degrees Réaumur. Enter a value to convert, or use the Kelvin to Réaumur chart further down the page.
Kelvin and degrees Réaumur are measured on scales with different zero points, so the conversion needs a formula rather than a single factor.
How to convert Kelvin to Réaumur
Kelvin and degrees Réaumur use different zero points, so you cannot convert them with a single multiplication. Apply the formula °Ré = (K − 273.15) × 4/5 instead.
°Ré = (K − 273.15) × 4/5
Worked example
Convert 300 K to degrees Réaumur:
300 K = 21.48 °Ré

What is a kelvin?
The kelvin is the SI base unit of temperature. It starts at absolute zero and uses the same degree size as Celsius, so 0 K equals −273.15 °C.
What is a degree Réaumur?
The Réaumur scale sets water’s freezing point at 0 °Ré and its boiling point at 80 °Ré. It is largely historical but survives in some cheese and syrup making.
Frequently asked questions
How many Réaumur are in a kelvin?
Kelvin and degrees Réaumur have no fixed ratio, because the two scales start at different zero points. Convert between them with °Ré = (K − 273.15) × 4/5 instead of multiplying by a single number.
How do you convert Kelvin to Réaumur?
Kelvin and degrees Réaumur use different zero points, so you cannot convert them with a single multiplication. Apply the formula °Ré = (K − 273.15) × 4/5 instead.
What is 10 Kelvin in Réaumur?
10 Kelvin equals -210.52 Réaumur. The conversion chart on this page lists the other values people look up most often.
