  2. Fahrenheit - Wikipedia

    en.wikipedia.org/wiki/Fahrenheit

    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 the lower ...

    1709 — Daniel Gabriel Fahrenheit constructed alcohol thermometers which were reproducible (i.e. two would give the same temperature) 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 ...

  6. Temperature - Wikipedia

    en.wikipedia.org/wiki/Temperature

    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.

    The answer to why the U.S. still uses Fahrenheit is simple: because it wants to. A law was signed in the 70s making the metric system, and Celsius an option, but workers in big industries, like ...

  8. Scale of temperature - Wikipedia

    en.wikipedia.org/wiki/Scale_of_temperature

    Scale of temperature. Scale of temperature is a methodology of calibrating the physical quantity temperature in metrology. Empirical scales measure temperature in relation to convenient and stable parameters or reference points, such as the freezing and boiling point of water. Absolute temperature is based on thermodynamic principles: using the ...

  9. Temperature measurement - Wikipedia

    en.wikipedia.org/wiki/Temperature_measurement

    A medical/clinical thermometer showing the temperature of 38.7 °C (101.7 °F) Temperature measurement (also known as thermometry) describes the process of measuring a current temperature for immediate or later evaluation. Datasets consisting of repeated standardized measurements can be used to assess temperature trends.
