What Is This Tool?

This tool enables the conversion of temperature intervals from degree centigrade (°C) to degree Réaumur (°r), assisting users in interpreting temperature differences for historical data, scientific research, and industrial applications.

How to Use This Tool?

  • Enter the temperature interval value in degree centigrade (°C).
  • Select degree centigrade as the input unit and degree Réaumur as the output unit.
  • Click the convert button to get the equivalent temperature interval in degree Réaumur (°r).

Key Features

  • Converts temperature intervals from °C to °r using the precise ratio of 1 °C = 0.8 °r.
  • Supports historical and scientific temperature analysis involving obsolete scales.
  • Browser-based and easy to use with straightforward input and output.

Examples

  • 10 °C equals 8 °r (10 × 0.8 = 8).
  • 25 °C equals 20 °r (25 × 0.8 = 20).

Common Use Cases

  • Analyzing temperature differences from historical Réaumur thermometer data.
  • Restoring and interpreting readings of antique scientific instruments.
  • Converting old industrial temperature data, such as in brewing, dairy, and sugar production.
  • Studying temperature intervals in thermodynamics and heat transfer applications.

Tips & Best Practices

  • Use this tool specifically for temperature interval conversions, not absolute temperatures.
  • Apply conversion when working with historical data or antique instrument readings.
  • Verify unit selection and input values carefully for accurate results.

Limitations

  • The degree Réaumur scale is mostly obsolete and rarely used in modern contexts.
  • This conversion only applies to temperature intervals, not absolute temperatures.
  • Converted values assume a linear scale without offset, limiting certain applications.

Frequently Asked Questions

Can this tool convert absolute temperatures between °C and °r?
No, this tool converts only temperature intervals, not absolute temperatures, since the scales have different zero points.

Why is degree Réaumur rarely used today?
Degree Réaumur is largely obsolete and mainly relevant for historical or antique instrument contexts.

What is the conversion rate between degree centigrade and degree Réaumur?
1 degree centigrade equals 0.8 degree Réaumur.

Key Terminology

Degree centigrade [°C]
Unit expressing temperature intervals on the Celsius scale; 1 °C interval equals 1 kelvin.
Degree Réaumur [°r]
Unit of temperature interval defined as 1/80 of the water boiling-freezing point difference; 1 °r = 1.25 kelvin.
Temperature interval
The difference or change in temperature between two points, without offset concerns.
