Weber (Wb): multiples and submultiples 
1 Wb = 1 Vs
1 Wb = 1 V·s = 1 T·m² = 1 J/A = 10^{8} Mx ( maxwells ) In physics, the weber is the unit of magnetic flux in the International System of Units (SI), whose units are voltsecond. A magnetic flux density of one Wb/m2 (one weber per square metre) is one tesla.
