Fahrenheit to Réaumur Conversion
Converting Fahrenheit (°F) to Réaumur (°Ré) is a common temperature conversion. 1 °F equals -13.777778 °Ré. For example, 100 °F is equal to 30.222222 °Ré.
Quick Mental Math: Fahrenheit to Réaumur
Divide by 2.25 to convert fahrenheit to reaumur.
Why is converting Fahrenheit to Réaumur tricky?
The conversion factor requires careful attention to avoid reversing the operation.
Reference Temperatures
Absolute zero: -459.67 °F = -218.52 °Ré. Water freezing point: 32 °F = 0 °Ré. Room temperature: 68 °F = 16 °Ré. Body temperature: 98.6 °F = 29.6 °Ré. Water boiling point: 212 °F = 80 °Ré.
What is Fahrenheit?
Fahrenheit (°F) is a unit of temperature. Fahrenheit is a temperature scale where water freezes at 32°F and boils at 212°F under standard atmospheric pressure. It defines temperature units based on intervals of 1/180th between these points. One degree Fahrenheit equals 5/9 of a kelvin or Celsius degree, making precise conversions essential in scientific and engineering contexts [cgpm-resolutions]. The Fahrenheit scale was created by Daniel Gabriel Fahrenheit in 1724 to provide a practical temperature measurement for weather and industrial processes. It was adopted widely in English-speaking countries and influenced early thermometry standards [nist-sp-811]. Fahrenheit remains the primary temperature scale in the United States and some Caribbean nations for everyday use. Scientific and international standards favor Celsius or kelvin, but Fahrenheit persists in HVAC, weather forecasting, and cooking within these regions [nist-sp-811].
What is Réaumur?
Réaumur (°Ré) is a unit of temperature. The Réaumur scale is a temperature scale where water freezes at 0 °Ré and boils at 80 °Ré at standard atmospheric pressure. Each degree Réaumur corresponds to 1.25 degrees Celsius. The scale was historically used in Europe but is now mostly obsolete and replaced by Celsius and Kelvin [cgpm-resolutions]. René Antoine Ferchault de Réaumur introduced the scale in 1730 to simplify temperature measurement using alcohol thermometers. It was widely used in France and parts of Europe until the 19th century before being supplanted by the Celsius scale [cgpm-resolutions]. Today, the Réaumur scale has limited use and appears mainly in historical or academic contexts. Some traditional cheese-making regions in Europe may still reference it. Modern science and industry prefer Celsius or Kelvin in line with SI standards [cgpm-resolutions].
Common Misspellings
People often search for this conversion using these alternate spellings: fahranheit, farenheit, fahrentheit, farhenheit, reaumer, reaumur, reaumur scale, réamer. All of these refer to the Fahrenheit to Réaumur conversion.
