Besides, what is the dimension of a constant?
Dimensional Constants
So there are other quantities that we are going to use, that is dimensional constant. So, dimensional constants are those quantities whose values are constant, and they possess dimensions. For example, Gravitational constant, Boltzmann constant, Planck's constant, etc.
Secondly, how do you find the dimension of a Boltzmann constant? Or, k = [M1 L2 T-2] × [M0 L0 T0 K1]-1 = [M1 L2 T-2 K-1]. Therefore, the Boltzmann constant is dimensionally represented as [M1 L2 T-2 K-1].
One may also ask, what is the dimension of Wien's constant?
b is a constant of proportionality called Wien's displacement constant, equal to 2.897771955 ×10−3 m⋅K, or b ≈ 2898 μm⋅K. This is an inverse relationship between wavelength and temperature.
