  Previously, we presented several empirical equations using the cosmic microwave background (CMB) temperature that were mathematically connected. Next, we proposed an empirical equation for the fine-structure constant. Considering the compatibility among these empirical equations, the CMB temperature (
  <em>T<sub>c</sub></em>) and gravitational constant (
  <em>G</em>) were calculated to be 2.726312 K and 6.673778 &#215; 10
  <sup>-11</sup> m
  <sup>3</sup>&#183;kg
  <sup>-1</sup>
  &#183;s
  <sup>-2</sup>, respectively. Every equation can be explained in terms of the Compton length of an electron (
  <em>λ<sub>e</sub></em>), the Compton length of a proton (
  <em>λ<sub>p</sub></em>) and α. However, these equations are difficult to follow. Using the correspondence principle with the thermodynamic principles in solid-state ionics, we propose a canonical ensemble to explain these equations in this report. For this purpose, we show that every equation can be explained in terms of Avogadro’s number and the number of electrons in 1 C.

However, these equations are difficult to follow. Our purpose in this report is to consider the physical meanings. Using the correspondence principle with the thermodynamic principles in solid-state ionics, we propose a canonical ensemble to explain these equations. For this purpose, we show that every equation can be explained in terms of Avogadro’s number and the number of electrons in 1 C. The remainder of this paper is organized as follows. In Section 2, we present the list of symbols used in our derivations. In Section 3, we discuss the purpose of this report. Using the correspondence principle with the thermodynamic principles in solid-state ionics, we try to show the canonical ensemble to explain these equations. In Section 4, we propose several equations that are functions of Avogadro’s number and the number of electrons in 1 C. In Section 5, using these equations, we explain our main equations. The remaining problems are discussed. In Section 6, our conclusions are described.</p></sec><sec id="s2"><title>2. Symbol List</title><sec id="s2_1"><title>2.1.
