x₁ is the Boltzmann k_B constant linking energy with temperature [approximately equal to: 1.380 6488(13)×10⁻²³ J/K], expressed in units x₂ (default: unitless/dimensionless and equal to 1) in paradigm/system/metaphysics/universe x₃ (default: this, our actual, physical universe)

Introduced by Planck (along with "h", his own eponymous constant); named after Boltzmann who nonetheless laid the foundation for research into such affairs. See also: stefanboltsemasi (sigma_SB), plankexu, tcelerita, gravnutnoia, avgadro, ocnerta, nejni, kelvo, nilgla.

In notes:

avgadro: x₁ is Avogadro constant N_A [approximately equal to: 6.02214129(27) × 10²³ mol^-1], expressed in units x₂ in paradigm/system/metaphysics/universe x₃ (default: this, our actual, physical universe).
entropi: x₁ (amount) is the entropy of system x₂ under conditions/in macrostate x₃, where the entropy is of type/calculated via formula x₄.
gravnutnoia: x₁ is Newton's constant of universal gravitation/G/big G [approximately equal to: 6.67×10⁽⁻¹¹⁾ N·(m/kg)² ] expressed in units x₂ (default: unitless/dimensionless and equal to 1) in paradigm/system/metaphysics/universe x₃ (default: this, our actual, physical universe)
plankexu: x₁ is the elementary unit (quantum) of angular momentum/half of Planck's reduced constant [id est: hbar/2 = h/(4 pi)] expressed in units x₂ (default: unitless/dimensionless and so that it is equal to 1) in paradigm/system/metaphysics/universe x₃ (default: this, our actual, physical universe)
stefanboltsemasi: x₁ is the black-body Stefan-Boltzmann sigma_SB constant [approximately equal to: 5.670373(21)×10⁽⁻⁸⁾ W/(m²×K⁴)], expressed in units x₂ (default: unitless/dimensionless and equal to pi^{2 / 480}) in paradigm/system/metaphysics/universe x₃ (default: this, our actual, physical universe)
tcelerita: x₁ (number; default: 1) is the physical speed supremum (for objects of positive masses)/celeritas/c₀ expressed in units x₂ (default: in terms of natural parameter c₀; id est: unitless/dimensionless and equal to 1) in (paradigm/system of) physics x₃ (default: this, our actual. physical universe and reality);
