What Is This Tool?

This online converter transforms temperature values from the Réaumur scale, a historical temperature measurement, to the Kelvin scale, the SI base unit for thermodynamic temperature. It helps interpret and convert legacy temperature data into a modern absolute scale used widely in science and engineering.

How to Use This Tool?

  • Enter the temperature value in Réaumur [°r]
  • Select Réaumur as the input unit and Kelvin as the output unit
  • Click the convert button to get the temperature in Kelvin [K]
  • Use the converted value for scientific analysis or reference

Key Features

  • Converts temperatures from Réaumur [°r] to Kelvin [K]
  • Based on the defined conversion rate: 1 °r equals 1.25 K
  • Supports interpreting historical meteorological and scientific records
  • Useful for calibrating antique thermometers and laboratory devices
  • Browser-based and easy to use without software installation

Examples

  • 10 °r converts to 12.5 K
  • 20 °r converts to 25 K

Common Use Cases

  • Interpreting historical climate and meteorological data recorded in °Ré
  • Calibrating or reading antique instruments that use the Réaumur scale
  • Converting traditional or legacy industrial temperature specifications referencing Réaumur
  • Applying thermodynamic temperature measurements in scientific research including cryogenics and astrophysics

Tips & Best Practices

  • Ensure the input temperatures are measured at standard atmospheric pressure for accurate conversion
  • Use converted Kelvin values in scientific calculations requiring absolute temperature
  • Recognize that Réaumur is largely obsolete and conversions serve mainly historical and specialized contexts
  • Double-check historical data context when interpreting old temperature records

Limitations

  • Réaumur is an outdated scale rarely used in modern measurements
  • Conversion assumes standard atmospheric pressure conditions
  • Kelvin is an absolute scale; be mindful of zero-point reference shifts when converting from relative scales
  • Conversion tool does not account for variations outside standard conditions

Frequently Asked Questions

What is the Réaumur temperature scale?
The Réaumur scale is a historical temperature measurement where 0 °Ré is the freezing point of water and 80 °Ré is the boiling point at standard atmospheric pressure.

How do I convert Réaumur to Kelvin?
Multiply the temperature in Réaumur by 1.25 to obtain the temperature in Kelvin.

Why is Kelvin used for temperature measurement?
Kelvin is the SI base unit for thermodynamic temperature, measured on an absolute scale with 0 K at absolute zero.

Key Terminology

Réaumur Scale
A historical temperature scale where 0 °Ré is freezing and 80 °Ré is boiling point of water at standard atmospheric pressure.
Kelvin
The SI base unit of thermodynamic temperature, defined with absolute zero as 0 K and equal magnitude to one degree Celsius.
Standard Atmospheric Pressure
A reference pressure condition under which the Réaumur scale is defined and conversion assumes validity.
