Delisle (°De)
Definition
Delisle (°De) is an inverted temperature scale where 0°De equals the boiling point of water and 150°De equals the freezing point. Higher values indicate colder temperatures.
History
The Delisle scale was invented in 1732 by Joseph-Nicolas Delisle, a French astronomer. It was used in Russia for nearly a century before being replaced by the Celsius and Réaumur scales.
Current use
The Delisle scale is no longer used in everyday practice. It appears in historical scientific literature and is of interest in the study of the history of thermometry and temperature measurement.
Fahrenheit (°F)
Definition
Fahrenheit (°F) is an imperial temperature scale where 32°F is the freezing point of water and 212°F is the boiling point of water at standard atmospheric pressure.
History
The Fahrenheit scale was proposed in 1724 by Daniel Gabriel Fahrenheit, a German-Dutch physicist. He based his scale on three reference points: brine freezing (0°F), water freezing (32°F), and human body temperature (96°F, later corrected to 98.6°F).
Current use
Fahrenheit is the primary temperature scale in the United States for weather, cooking, and everyday use. It is also used in some Caribbean countries and occasionally in the United Kingdom alongside Celsius.
