To convert 2.07*10^-15 Webers in MKS units to SI units, no conversion is necessary as Weber is already an SI unit for magnetic flux. The discussion clarifies that Weber is part of the SI system, specifically within the mKgs framework. Participants confirm that the value remains the same and does not require any multiplication or adjustment. A reference to a NIST website is provided for further clarification on unit definitions. Overall, the conversation emphasizes the understanding that Webers are already expressed in SI units.
