Réaumur (°Ré) and Fahrenheit (°F) are temperature scales used in different regions and fields. While both measure temperature, they use different reference points.
Réaumur is a historical temperature scale that sets the freezing and boiling points of water at 0 and 80 degrees.
Réaumur is mostly of historical interest but still appears in some traditional recipes and older scientific texts.
Fahrenheit is a temperature scale primarily used in the United States and a few other regions.
Many people find Fahrenheit useful for describing everyday weather conditions because it provides more temperature intervals between common outdoor temperatures.
| Feature | Réaumur (°Ré) | Fahrenheit (°F) |
|---|---|---|
| Water Freezes | 0 °Ré | 32°F |
| Water Boils | 80 °Ré | 212°F |
| Primary Usage | Historical (Europe) | United States |
| Scientific Use | Rarely used | Rarely used |
| Weather Forecasts | Not used | Common in U.S. |
