  2. List of physical constants - Wikipedia

    en.wikipedia.org/wiki/List_of_physical_constants

    The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured.

    en.wikipedia.org/wiki/List_of_letters_used_in...

    Latin and Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.

  6. List of physical quantities - Wikipedia

    The table usually lists only one name and symbol that is most commonly used. The final column lists some special properties that some of the quantities have, such as their scaling behavior (i.e. whether the quantity is intensive or extensive ), their transformation properties (i.e. whether the quantity is a scalar , vector , matrix or tensor ...

    [54] [5] [55] [56] The unit's symbol K is a capital letter, [39] per the SI convention to capitalize symbols of units derived from the name of a person. [57] It is common convention to capitalize Kelvin when referring to Lord Kelvin [5] or the Kelvin scale. [58] The unit symbol K is encoded in Unicode at code point U+212A KELVIN SIGN.

  9. 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 ...
