x + 459.67 °Ra. The Fahrenheit scale (/ ˈfærənhaɪt, ˈfɑːr -/) is a temperature scale based on one proposed in 1724 by the European physicist Daniel Gabriel Fahrenheit (1686–1736). [1] It uses the degree Fahrenheit (symbol: °F) as the unit. Several accounts of how he originally defined his scale exist, but the original paper suggests ...
Daniel Gabriel Fahrenheit FRS (/ ˈfærənhaɪt /; German: [ˈfaːʁn̩haɪt]; 24 May 1686 – 16 September 1736) [ 1 ] was a physicist, inventor, and scientific instrument maker, born in Poland to a family of German extraction. Fahrenheit invented thermometers accurate and consistent enough to allow the comparison of temperature measurements ...
Units in everyday use by country as of 2019 The history of the metric system began during the Age of Enlightenment with measures of length and weight derived from nature, along with their decimal multiples and fractions. The system became the standard of France and Europe within half a century. Other measures with unity ratios [Note 1] were added, and the system went on to be adopted across ...
1714 — Daniel Gabriel Fahrenheit invents the mercury-in-glass thermometer giving much greater precision (4 x that of Rømer). Using Rømer's zero point and an upper point of blood temperature, he adjusted the scale so the melting point of ice was 32 and the upper point 96, meaning that the difference of 64 could be got by dividing the ...
Thermometer with Fahrenheit (symbol °F) and Celsius (symbol °C) units. In 1714, scientist and inventor Daniel Gabriel Fahrenheit invented a reliable thermometer, using mercury instead of alcohol and water mixtures. In 1724, he proposed a temperature scale which now (slightly adjusted) bears his name.

He also contends in the work that Shakespeare "invented" humanity, in that he prescribed the now-common practice of "overhearing" ourselves, which drives our changes. The two paragons of his theory are Sir John Falstaff of Henry IV and Hamlet , whom Bloom sees as representing self-satisfaction and self-loathing, respectively.
In the United States, the Fahrenheit scale is the most widely used. On this scale the freezing point of water corresponds to 32 °F and the boiling point to 212 °F. The Rankine scale, still used in fields of chemical engineering in the US, is an absolute scale based on the Fahrenheit increment.
