Fahrenheit (°F) and Réaumur (°Ré) are temperature scales used in different regions and fields. While both measure temperature, they use different reference points.
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.
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.
| Feature | Fahrenheit (°F) | Réaumur (°Ré) |
|---|---|---|
| Water Freezes | 32°F | 0 °Ré |
| Water Boils | 212°F | 80 °Ré |
| Primary Usage | United States | Historical (Europe) |
| Scientific Use | Rarely used | Rarely used |
| Weather Forecasts | Common in U.S. | Not used |
