Weber (unit)

Physical unit
Unit name	Weber
Unit symbol	${\displaystyle \mathrm {Wb} }$
Physical quantity (s)	Magnetic river
Formula symbol	${\displaystyle \Phi }$
dimension	${\displaystyle {\mathsf {M\;L^{2}\;T^{-2}\;I^{-1}}}}$
system	International system of units
In SI units	${\displaystyle \mathrm {1\,Wb=1\;{\frac {kg\,m^{2}}{A\,s^{2}}}=1\;V\,s} }$
In CGS units	${\displaystyle \mathrm {1\,\,Wb\,\,{\mathrel {\widehat {=}}}\,10^{8}\;Mx} }$
Named after	Wilhelm Eduard Weber
Derived from	Volt , second
See also: Maxwell

The Weber (also: the volt second ) is the unit of measurement of magnetic flux . It was named after Wilhelm Eduard Weber .

${\displaystyle \mathrm {1\,Wb=1\,V\,s=1\,T\,m^{2}} }$

In the outdated CGS system , Mx ( Maxwell ) is the unit of magnetic flux.

${\displaystyle \mathrm {1\,Wb\,\,{\mathrel {\widehat {=}}}\,\,10^{8}\,Mx} }$

Due to the different size systems , however, the difference between the two units is not just one factor (hence the sign ≙ ).
