The MKS unit for magnetic flux is the Weber. Magnetic flux is a measure of the quantity of magnetism, considering the strength and extent of a magnetic field. It is defined as the integral of the magnetic field over a given area and is expressed in terms of magnetic flux density (magnetic field strength) multiplied by the area through which the field lines pass.

In the MKS system (Meter-Kilogram-Second system), one Weber is defined as the flux that, when linked with a circuit of one turn, induces an electromotive force of one volt as the magnetic field changes at the rate of one weber per second. This relationship underscores the importance of the Weber as a fundamental unit in electromagnetism.

Other units listed address different physical quantities: Tesla is a unit of magnetic flux density, Henry is the unit of inductance, and Gauss is a smaller unit of magnetic flux density commonly used in the CGS (centimeter-gram-second) system. While these units are relevant in the study of electromagnetism, they are not equivalent to the unit of magnetic flux itself, which is specifically the Weber in the MKS system.
