m^2*kg*s^-2*K-1
m = metres, kg = kilograms, s = seconds, K = Kelvin.
Boltzmann's constant relates the average kinetic energy of particles in a gas with the temperature of the gas.
The value of the constant, better known as the Stefan–Boltzmann constant is given, in SI units byσ = 5.670373×10^−8 W m^−2 K^−4W = Wattsm = metresK = Kelvin
Boltzmann's constant (not bolt'z man's!) is 1.38064852*10-23 m2 kg s-2 K-1
The dimensions are [L^2MT^(-2)K^(-1)]whereL = lengthM = MassT = TimeK = Temperature
They are not the same, but related. From Wikipedia (article "gas constant"): " [The gas constant] is equivalent to the Boltzmann constant, but expressed in units of energy (i.e. the pressure-volume product) per temperature increment per mole (rather than energy per temperature increment per particle)".
In the SI system the radiation constant (Stefan-Boltzmann constant) is measured in W/m2.K4.

Using Stefan's law to find the emittance of a bodies radiation in Watts. F( force in Watts--unit time per unit surface) = (a constant called the Stefan-Boltzmann constant )* T4 (temperature in Kelvin )
The amount of heat radiated by a person in a given environment can be calculated using the Stefan-Boltzmann Law, which relates the temperature of the person and the surrounding environment to the rate at which heat is radiated. This formula takes into account the person's surface area and the Stefan-Boltzmann constant.
Boltzmann's constant relates the average kinetic energy of particles in a gas with the temperature of the gas.
The Stefan-Boltzmann radiation law states that the total radiant heat energy emitted by a blackbody is directly proportional to the fourth power of its temperature. This means that as the temperature of a blackbody increases, the amount of radiation it emits also increases significantly. The law is described by the equation P = σ * A * T^4, where P is the power emitted, A is the surface area, T is the temperature in Kelvin, and σ is the Stefan-Boltzmann constant.
The value of the constant, better known as the Stefan–Boltzmann constant is given, in SI units byσ = 5.670373×10^−8 W m^−2 K^−4W = Wattsm = metresK = Kelvin
The relation between temperature and energy is given by the Boltzmann equation. Boltzmann found a consatn( called the boltzmann constant) that relates the two. That is Energy=k*T
They do work, they use the Stefan-Boltzmann law (related to radiation of hot bodies)
The Boltzmann constant (kB or k), named after Ludwig Boltzmann, is a physical constant relating energy at the individual particle level with temperature.It is the gas constant R divided by the Avogadro constantIt has the same dimension (energy divided by temperature) as entropy. The accepted value in SI units is 1.3806488(13)×10−23 Joule/degree KFor more information refer to link below.
The Boltzmann constant (k) is a fundamental constant in thermodynamics that relates the average kinetic energy of particles in a system to its temperature. It plays a crucial role in determining the behavior of gases and understanding the relationship between temperature and energy in physical systems.
