About the Magnetic Flux Converter

Magnetic flux is the total B field passing through an area and is measured in webers. Induced-voltage calculations, transformer design, and flux-meter readings use it; maxwell is the historical CGS unit. This page retains the standard SI relationship while keeping customary and legacy units explicit, which is important when a specification crosses disciplines.

Enter a value to see the conversion immediately—for example, 1 maxwell equals exactly 1e-8 webers. For a related check, use the Magnetic Flux Density Converter and Magnetic Field Strength Converter; those tools describe a different but commonly connected quantity.
