Quick Mental Math: Fahrenheit to Delisle
Divide by 1.20 to convert fahrenheit to delisle.
Why is converting Fahrenheit to Delisle tricky?
The conversion factor requires careful attention to avoid reversing the operation.
Reference Temperatures
Absolute zero: -459.67 °F = 559.725 °De. Water freezing point: 32 °F = 150 °De. Room temperature: 68 °F = 120 °De. Body temperature: 98.6 °F = 94.5 °De. Water boiling point: 212 °F = 0 °De.
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 Delisle?
Delisle (°De) is a unit of temperature. The Delisle scale measures temperature with zero at the boiling point of water and increasing values downward. One degree Delisle equals 2/3 of a degree Celsius, making it inversely proportional to Celsius. This scale is now mostly historical and not used in modern thermometry [cgpm-resolutions]. Invented by Joseph-Nicolas Delisle in 1732, the scale was devised for scientific observations in Russia. It fixed 0 °De at 100 °C (water boiling point) and increased toward freezing point, opposite to Celsius. The scale fell out of use in favor of Celsius and Kelvin as international standards emerged [cgpm-resolutions]. The Delisle scale is obsolete and retained only in historical scientific texts and specialized archival references. Modern temperature measurements universally use Celsius, Fahrenheit, or Kelvin. Organizations like BIPM do not recognize Delisle for current temperature calibration [bipm-si-brochure].
Common Misspellings
People often search for this conversion using these alternate spellings: fahranheit, farenheit, fahrentheit, farhenheit, Delislee, Delisleu, Delisell, Delislee scale, Delisle temperature. All of these refer to the Fahrenheit to Delisle conversion.
