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.
k represents the unit prefix kilo-(10 3) [10] the Boltzmann constant, often represented as k B to avoid confusion; the angular wavenumber of the wave equation, the magnitude of the wave vector k; an integer, e.g. a dummy variable in summations, or an index of a matrix; an unspecified (real) constant; the spring constant of Hooke's law
kelvin (K) Θ or [K] intensive, scalar: Electric Current: I: Rate of flow of electrical charge per unit time: ampere (A) I: extensive, scalar: Angle: ∠ the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. radian (rad) ∠ BAC: extensive, scalar: Luminous intensity: I v
K thermodynamic temperature "The kelvin, symbol K, is the SI unit of thermodynamic temperature. It is defined by taking the fixed numerical value of the Boltzmann constant k to be 1.380 649 × 10 −23 when expressed in the unit J K −1, which is equal to kg m 2 s −2 K −1, where the kilogram, metre and second are defined in terms of h, c ...
The Boltzmann constant (k B or k) is the proportionality factor that relates the average relative thermal energy of particles in a gas with the thermodynamic temperature of the gas. [2] It occurs in the definitions of the kelvin (K) and the gas constant , in Planck's law of black-body radiation and Boltzmann's entropy formula , and is used in ...
