Accuracy

Note: You can increase or decrease the accuracy of this answer by selecting the number of significant figures required from the options above the result.

Réaumur = (Delisle - -100) / 1.87500001

Réaumur = (1 - -100) / 1.87500001

Réaumur = 101 / 1.87500001

Réaumur = 53.86666638

## Delisle to Réaumur (°De to ºRé) formula

Réaumur = (Delisle - -100) / 1.87500001

The Delisle scale is a temperature scale that was developed by French astronomer Joseph-Nicolas Delisle in the early 18th century. It is named after him and is based on the Celsius scale, which is widely used today. The Delisle scale is a reverse scale, meaning that as the temperature increases, the Delisle value decreases.

On the Delisle scale, the boiling point of water is set at 0 degrees, while the freezing point is set at 150 degrees. This means that the Delisle scale has a larger range than the Celsius scale, with 180 degrees between the boiling and freezing points. To convert a temperature from Delisle to Celsius, you can use the formula: Celsius = (150 - Delisle) * 2/3.

While the Delisle scale was widely used in the 18th century, it has since fallen out of favor and is not commonly used today. The Celsius scale, on the other hand, is the most widely used temperature scale in the world, particularly in scientific and everyday applications. It is based on the freezing and boiling points of water, making it a practical and easily understandable scale for measuring temperature.

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.
