Conversion of Magnetic Units from SI System to CGS System
International System (SI) and Gaussian System (CGS)
In the International System of Units, the unit system for electromagnetics is the MKSA rational system, which specifies the units for the four fundamental physical quantities in electromagnetics, namely, the units for length, mass, time, and current intensity, which are meters (m), kilograms (kg), seconds (s), and amperes (A), respectively.
The Gaussian unit system is established on the basis of the absolute electrostatic unit system (CGSE unit system or e.s.u) and the absolute electromagnetic unit system (CGSM unit system or e.m.u) in electromagnetism. Simply put, the Gaussian unit system is an electromagnetic unit system that summarizes the above two unit systems, also known as the mixed unit system. The absolute electrostatic unit system selects length, mass, and time as the basic quantities, with units of cm g、s。
The Conversion Relationship between SI System and CGS System
The quantity of SI system can be multiplied by the conversion ratio in the following table to obtain the quantity of CGS system. Due to the complex conversion relationship, the specific derivation process will not be elaborated here. Interested friends can read the next book "Electromagnetic Unit System" (edited by Hu Youqiu).
