Rankine To Reaumur (°R To °Ré) Converter

The Rankine to Réaumur (°R to °Ré) Converter is a handy tool designed to help you easily convert temperatures from the Rankine scale to the Réaumur scale. Whether you’re working with scientific data, engineering projects, or educational purposes, this converter simplifies the process of translating temperature measurements between these two units.

The Rankine scale (°R) is an absolute temperature scale primarily used in engineering, especially in the United States. It starts at absolute zero, like the Kelvin scale, but uses degrees similar in size to Fahrenheit. One degree Rankine is equivalent to one degree Fahrenheit, and the scale ranges from absolute zero (0°R) upward.

The Réaumur scale (°Ré), also known as the Reaumur scale, was historically used in some European countries. It is based on the freezing point of water being 0°Ré and the boiling point at 80°Ré under standard atmospheric pressure. Each degree Réaumur is 1/80th of the temperature difference between freezing and boiling points of water.

To convert from Rankine to Réaumur, you can use the following formula:
°Ré = (°R – 491.67) × 0.8

Here, subtract 491.67 from the Rankine temperature to convert it to Fahrenheit, then multiply by 0.8 to get the temperature in Réaumur. This formula helps you quickly switch between these two temperature units with ease, making your calculations more straightforward and accurate.
