✅ Réaumur to Celsius Converter FAQ

✔️ How to convert °Ré to °C?

If you need to convert degrees Réaumur (°Ré) to degrees Celsius (°C), you can use the following formula: °C = °Ré / 0,8. In other words, all you need to do is divide the value in Réaumur by 0.8.

✔️ What is the formula to change °Ré into °F?

In order to convert degrees Réaumur to Fahrenheit, you can use the following formula: °F = °Ré / 0,8 x 9/5 + 32.

✔️ Is 40°Ré hot or cold?

40 degrees Réaumur (50 degrees Celsius and 122 degrees Fahrenheit) is considered hot. For example, the hottest temperature ever recorded on Earth was 45°Ré, which is slightly higher. This temperature feels extremely uncomfortable and can be dangerous for one’s health.
