About magnetic flux units

Magnetic flux is the total magnetic field passing through a surface. One weber equals one volt-second or one tesla·square metre; the CGS maxwell is 10⁻⁸ Wb.

Frequently asked questions

What is the SI unit of magnetic flux?

This converter uses the weber (Wb) as its reference unit; every other unit is defined relative to it.

How many magnetic flux units can I convert?

7 units are supported here, across SI, CGS systems. Every pair can be converted in both directions.
