Convert Reaumur to kelvin
Please provide values below to convert Reaumur [°r] to kelvin [K], or Convert kelvin to Reaumur.
How to Convert Reaumur to Kelvin
The conversion between Reaumur and kelvin is not linear or involves a specific formula. Please use the calculator above for an accurate conversion.
To convert from Reaumur to the base unit, the formula is: y = Reaumur * (4/5) + 273.15
To convert from the base unit to kelvin, the formula is: y = base_unit_value

Reaumur
The Reaumur is a temperature scale where 0°r is the freezing point of water and 80°r is the boiling point under standard conditions.
History/Origin
Developed by René Antoine Ferchault de Réaumur in 1730, it was widely used in Europe for scientific and industrial purposes before being largely replaced by Celsius and Fahrenheit scales.
Current Use
The Reaumur scale is now rarely used, primarily in some regions of France and historical contexts, with most temperature measurements adopting Celsius or Fahrenheit.
Kelvin
The kelvin (K) is the base unit of temperature in the International System of Units (SI), defined as 1/273.16 of the thermodynamic temperature of the triple point of water.
History/Origin
The kelvin was established in 1848 by Lord Kelvin (William Thomson) as a temperature scale based on absolute zero, replacing earlier thermodynamic temperature scales. It was officially adopted as an SI base unit in 1960.
Current Use
The kelvin is used worldwide in scientific and engineering contexts to measure thermodynamic temperature, especially in physics, chemistry, and related fields, providing a standard for temperature measurement without negative values.
