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. Many of these are redundant, in the sense that they obey a known relationship with other physical ...
A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
A mathematical constant is a number whose value is fixed by an unambiguous definition, often referred to by a special symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1] Constants arise in many areas of mathematics, with constants such as e and π occurring in such ...

A physical constant, sometimes fundamental physical constant or universal constant, is a physical quantity that cannot be explained by a theory and therefore must be measured experimentally. It is distinct from a mathematical constant , which has a fixed numerical value, but does not directly involve any physical measurement.
Coulomb constant: Amedeo Avogadro: 1776–1856 Italian: Avogadro constant: Michael Faraday: 1791–1867 British Faraday constant: Johann Josef Loschmidt: 1821–1895 Austrian: Loschmidt constant: Johann Jakob Balmer: 1825–1898 Swiss: Balmer's constant: Josef Stefan: 1835–1893 Slovene/Austrian: Stefan's constant [2] Ludwig Boltzmann: 1844 ...
This is because constants, by definition, do not change. Their derivative is hence zero. Conversely, when integrating a constant function, the constant is multiplied by the variable of integration. During the evaluation of a limit, a constant remains the same as it was before and after evaluation.
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 ...
