I need to convert mj/mm^2 to bar is there a way to do that ? I think we cannot ,bar is N/m^2 but we have j/m^2

One unit is an energy per area (energy density), but the other is a force per area (pressure). They have different dimensions and thus measure different things.

Yes I agree, thanks

So I needed to convert 0.55mj/mm^2 to bar

Still true.

I just skimmed that article, but it seems to say there are two ways of producing shockwaves. One of those ways can be characterized by the pressure used (compressed air), the other by the energy (magnetic). They are claiming they produce equivalent shock waves. Looks like some empirical chart.

(It's not a simple unit conversion, since those units are not measuring the same thing.)

Okay well I ll just show them the article since they are expert and I am sure they can deduce something from it
