Gabriel David Fahrenheit

Gabriel David Fahrenheit

1686-1736

German physicist and instrument maker who invented the mercury thermometer (in 1714) and developed the Fahrenheit temperature scale. The thermometer, however, was not generally adopted as a clinical instrument until the 1860s. Because the zero point on Fahrenheit's original scale was the temperature of an ice-salt mixture, the freezing point of water on his scale is 32°, normal body temperature is 98.6°, and the boiling point of water is 212°. Although the Fahrenheit scale is still commonly used in the United States, scientists and most other nations have adopted the Celsius scale.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content.

  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
