Convert Celsius (°C) to Réaumur (°Ré)
Conversion:
1 Celsius (°C) = 0.8 Réaumur (°Ré)
How to Convert Celsius (°C) to Réaumur (°Ré)
1 c = 0.8 re
1 re = 1.25 c
Example: convert 15 Celsius (°C) to Réaumur (°Ré):
25 c = 20 re

Celsius (°C)
Definition
Celsius (°C) is a metric temperature scale where 0°C is the freezing point of water and 100°C is the boiling point of water at standard atmospheric pressure.
History
The Celsius scale was proposed in 1742 by Anders Celsius, a Swedish astronomer. His original scale was inverted (0° for boiling, 100° for freezing), and was later reversed by Carl Linnaeus or Daniel Ekström.
Current use
Celsius is the most widely used temperature scale in the world, standard in most countries for weather forecasts, cooking, scientific research, and everyday temperature measurements. Only the US, Liberia, and the Cayman Islands primarily use Fahrenheit.
Réaumur (°Ré)
Definition
Réaumur (°Ré) is a temperature scale where 0°Ré equals the freezing point of water and 80°Ré equals the boiling point of water.
History
The Réaumur scale was proposed in 1730 by René Antoine Ferchault de Réaumur, a French scientist. It was widely used across Europe, particularly in France, Germany, and Russia, until the late 19th century.
Current use
The Réaumur scale is nearly obsolete but still occasionally referenced in European cheese-making and some Italian candy-making traditions. It also appears in historical scientific texts.
