Convert Fahrenheit to Reaumur

The Fahrenheit scale was developed by the German physicist Daniel Gabriel Fahrenheit in the early 18th century, specifically in 1724. Fahrenheit chose 32°F as the freezing point of water and 212°F as the boiling point of water under normal atmospheric pressure. The scale was based on several reference points, including the freezing point of water, the temperature of a mixture of ice and salt (which he set to 0°F), and the human body temperature, which he initially set at 96°F (later adjusted to 98.6°F). The Fahrenheit scale was widely used in English-speaking countries, particularly the U.S., until the adoption of the Celsius and Kelvin scales in scientific communities. It remains in common use for everyday temperature measurements in the U.S. and some Caribbean nations.

The Réaumur scale was developed by the French scientist René Antoine Ferchault de Réaumur in 1730. Réaumur created this scale based on the properties of water and the idea of dividing the temperature range between freezing and boiling points into 80 intervals, making it convenient for use in industries like brewing and metallurgy. The scale was once widely used in Europe, particularly in France, Germany, and parts of Russia. However, it was eventually supplanted by the Celsius scale, which became more universally adopted due to its simplicity and consistency with the metric system. Despite this, the Réaumur scale is still of historical interest and is sometimes used in specialized fields such as certain aspects of thermometry and scientific research.
