Griffiths is showing magnetic field to be tesla. And mag flux to be weber. And H to be amp/meter. Jackson agrees with mag flux and calls it a weber. However, he calls "mag field", H, amp/meter and tesla, B, "mag induction". It would be nice if there was some consistancy here. ;-( OK, I suppose we should go with NIST definitions for SI? They agree with Jackson for mag flux as weber and magnetic field strength as H, amp/meter. But they call B, tesla, "magnetic flux density" which looks OK to me since it is weber/m^2. So how about going with the NIST definitions so we can all be on the same page? Is magnetic intensity the same as mag flux density? You had the conversion for mag flux density (intensity?) as a tesla; it has to be tesla^-1 in order for mag flux density to be dimensionless.

That is why all the conversion factors are in powers of a tesla (kg/coul-sec). It is interesting that the conversion for E is 1/tesla while displacement, D, is tesla. This is strange as the conversion from CGS to your units for E and D would be the same since they have the same units. ??? | Now, what can we glean from this?
