The Conversion Formula
Temperature conversions between celsius 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 °C gives 20 °Re, and converting 100 °C gives 80 °Re.
About celsius
The Celsius scale is named after Swedish astronomer Anders Celsius. In 1742, he created a scale based on 0 for the boiling point of water and 100 for the freezing point. This was later inverted to the familiar 0-100 scale we use today by Carl Linnaeus and others. For a long time, it was known simply as 'centigrade' (meaning 100 steps) until it was officially renamed Celsius in 1948 to honor its inventor. celsius are commonly used in Weather forecasting (Global), Cooking and baking (Global), Medical body temperature, and Scientific research, Computer hardware monitoring.
Water freezes at 0°C and boils at 100°C.
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.
