This is a collection of temperature conversion formulas and comparisons among eight different temperature scales, several of which have long been obsolete.. Temperatures on scales that either do not share a numeric zero or are nonlinearly related cannot correctly be mathematically equated (related using the symbol =), and thus temperatures on different scales are more correctly described as ...
The Celsius, Fahrenheit, and Rankine scales were redefined in terms of the Kelvin scale using this definition. [ 2 ] [ 7 ] [ 8 ] The 2019 revision of the SI now defines the kelvin in terms of energy by setting the Boltzmann constant to exactly 1.380 649 × 10 −23 joules per kelvin ; [ 2 ] every 1 K change of thermodynamic temperature ...
The Fahrenheit scale (/ ˈ f æ r ə n h aɪ t, ˈ f ɑː r-/) 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.
The Rankine scale is used in engineering systems where heat computations are done using degrees Fahrenheit. [3] The symbol for degrees Rankine is °R [2] (or °Ra if necessary to distinguish it from the Rømer and Réaumur scales). By analogy with the SI unit kelvin, some authors term the unit Rankine, omitting the degree symbol. [4] [5]
Fahrenheit's scale is still in use in the United States for non-scientific applications. Temperature is measured with thermometers that may be calibrated to a variety of temperature scales . In most of the world (except for Belize , Myanmar , Liberia and the United States ), the Celsius scale is used for most temperature measuring purposes.

Also Turks and Caicos Islands use Fahrenheit; Bermuda, Antigua and Barbuda and other islands which use the same meteorological service (Anguilla, British Virgin Islands, Montserrat and Saint Kitts and Nevis) use both Fahrenheit and Celsius
A medical thermometer showing a temperature reading of 38.7 °C (101.7 °F). Taking a human's temperature is an initial part of a full clinical examination.There are various types of medical thermometers, as well as sites used for measurement, including:
