The Conversion Formula

Temperature conversions between fahrenheit and réaumur use specific formulas rather than a simple multiplication factor, because temperature scales have different zero points. Use the converter above or the reference table for quick lookups. For example, converting 25 °F gives -3.1111 °Re, and converting 100 °F gives 30.2222 °Re.

About fahrenheit

The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in 1724. He was the first to use mercury in thermometers, making them much more accurate. He defined 0°F as the temperature of a specific ice-salt brine mixture, and roughly 96°F as the human body temperature. While replaced by Celsius in most countries during the 20th century, Fahrenheit remains the official scale of the United States, valued by some for its more granular degrees for weather. fahrenheit are commonly used in Weather forecasting (US), Oven temperatures (US), Home thermostats (US), and Pool and spa settings, Old medical texts.

Room temperature is roughly 70°F.

About réaumur

The Réaumur scale was defined by René Antoine Ferchault de Réaumur in 1730. He set the freezing point of water at 0° and the boiling point at 80°. Why 80? He believed alcohol expanded 80 parts per 1000 when heated. This scale was once very popular in Europe, especially in France and Russia (it's mentioned often in Dostoevsky's novels). Today, it is mostly obsolete, though still used in some Italian cheese production. réaumur are commonly used in Parmigiano-Reggiano cheese making, Historical literature, 19th-century medical records, and Old candy making recipes.

Water boils at 80°Re.

When Would You Convert fahrenheit to réaumur?
