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 = (Rømer - 7.5) * 1.52380952

Réaumur = (1 - 7.5) * 1.52380952

Réaumur = -6.5 * 1.52380952

Réaumur = -9.90476188

## Rømer to Réaumur (°Rø to ºRé) formula

Réaumur = (Rømer - 7.5) * 1.52380952

Rømer is an historical figures who made significant contributions to the field of temperature measurement.

Ole Rømer, a Danish astronomer, is known for his work in the late 17th century, where he made important observations and calculations related to the speed of light. However, Rømer also made contributions to temperature measurement by developing the Rømer scale. The Rømer scale, also known as the Danish scale, was based on the freezing and boiling points of water, similar to the Celsius scale. However, Rømer's scale used different reference points, with 0 degrees representing the freezing point of brine (a mixture of water and salt) and 60 degrees representing the boiling point of water. While the Rømer scale is no longer widely used, it played a role in the development of temperature measurement and served as an early precursor to the Celsius scale.

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.
