Physics a level magnetism question

Guys, I need your help, I don't get how to derive a Weber or Tesla in SI units? I know that one Tesla is 1Wb/m^(-2), but how do I break down a Weber into SI units?

Thanks!

You can use the “defining equation” for the magnetic force to find the SI unit of the magnetic field:

F = BIL

B = \dfrac{F}{IL}

where the direction of the current is perpendicular to the direction of the magnetic field

As for the SI unit,

[ B ] = \dfrac{[F]}{[IL]}

[ B ] = \dfrac{[ \text{kg m } \text{s}^{-2}]}{[ \text{A m}]}
