  2. Conversion of scales of temperature - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_scales_of...

    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 ...

  3. Rankine scale - Wikipedia

    en.wikipedia.org/wiki/Rankine_scale

    Similar to the Kelvin scale, which was first proposed in 1848, [1] zero on the Rankine scale is absolute zero, but a temperature difference of one Rankine degree (°R or °Ra) is defined as equal to one Fahrenheit degree, rather than the Celsius degree used on the Kelvin scale.

  4. Temperature - Wikipedia

    en.wikipedia.org/wiki/Temperature

    As a collection of classical material particles, the temperature is a measure of the mean energy of motion, called translational kinetic energy, of the particles, whether in solids, liquids, gases, or plasmas. The kinetic energy, a concept of classical mechanics, is half the mass of a particle times its speed squared.

  5. Fahrenheit - Wikipedia

    en.wikipedia.org/wiki/Fahrenheit

    For an exact conversion between degrees Fahrenheit and Celsius, and kelvins of a specific temperature point, the following formulas can be applied. Here, f is the value in degrees Fahrenheit, c the value in degrees Celsius, and k the value in kelvins: f °F to c °C: c = ⁠ f − 32 / 1.8 ⁠

  6. Thermoelectric effect - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_effect

    v. t. e. The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple. [1] A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, heat is transferred from one side to the other, creating a ...

  7. Rømer scale - Wikipedia

    en.wikipedia.org/wiki/Rømer_scale

    1 °Rø = ⁠ 40 / 21 ⁠ °C = ⁠ 24 / 7 ⁠ °F. Conversion between temperature scales. The Rømer scale (Danish pronunciation: [ˈʁœˀmɐ]; notated as °Rø), also known as Romer or Roemer, is a temperature scale named after the Danish astronomer Ole Christensen Rømer, who developed it for his own use in around 1702. It is based on the ...

  8. kT (energy) - Wikipedia

    en.wikipedia.org/wiki/KT_(energy)

    kT (also written as k B T) is the product of the Boltzmann constant, k (or k B), and the temperature, T.This product is used in physics as a scale factor for energy values in molecular-scale systems (sometimes it is used as a unit of energy), as the rates and frequencies of many processes and phenomena depend not on their energy alone, but on the ratio of that energy and kT, that is, on ⁠ E ...

  9. 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 ...
