Celsius = Réaumur * 1.25

Celsius = 1 * 1.25

Celsius = 1.25

Réaumur to Celsius (ºRé to ºC) formula

Celsius = Réaumur * 1.25

Réaumur is a temperature scale that were widely used in the past, particularly in Europe. The Réaumur scale, named after the French physicist René Antoine Ferchault de Réaumur, was developed in the early 18th century. On this scale, the freezing point of water is set at 0°Ré and the boiling point at 80°Ré, with the scale divided into 80 equal parts or degrees. The Réaumur scale was commonly used in scientific research and engineering applications in Europe until it was gradually replaced by the Celsius scale.

While the Réaumur scale is no longer commonly used, it played a significant role in the history of temperature measurement. The Celsius scale, on the other hand, has become the international standard for temperature measurement, providing a common language for scientists, engineers, and individuals worldwide.

Celsius and Kelvin are two commonly used temperature scales in the field of science and everyday life. The Celsius scale, also known as the centigrade scale, is named after the Swedish astronomer Anders Celsius. It is based on the concept of dividing the range between the freezing and boiling points of water into 100 equal intervals. The freezing point of water is defined as 0 degrees Celsius, while the boiling point is defined as 100 degrees Celsius at standard atmospheric pressure.

The Celsius scale is commonly used in weather forecasts, household thermometers, and cooking, while the Kelvin scale is primarily used in scientific experiments, thermodynamics, and calculations involving gases.
