Formula to Convert °Re – °C

In mathematical terms, this conversion uses the formula that is shown below and it is the same formula used by the Celsius – Reaumur – Celsius to give you the most accurate conversion. For instance, 9°Re = 11.25°C and 32°Re = 40°C

[number of] °Re / 0.8 = [number of] °C 

When to use Reaumur?

Although previously used as a widespread scale for measuring temperature, Reaumur is used now in cheese production to measure the temperature of milk. It is also used in cooking desserts to measure the temperature of certain ingredients, but mainly only used in Europe. It had been replaced by Celsius by the mid-19th century. Above you will be able to convert Reaumur to Celsius.

When to use Celsius?

Degrees Celsius is the most common form of measuring temperature used in thermometers and on the news when telling the weather. The name Celsius comes from the Swedish astronomer Anders Celsius who discovered a temperature scale where 0 signified boiling water and 100 freezing water. It was formerly known as degrees centigrade. Use our Re to C conversion tool above.
