Exterior coating/ paint material comparison

Hi all, has anyone looked into exterior coating EPD comparisons? What is a best practice to make EPD’s comparable to each other in terms of units. I have some coating materials measured in kg or m2. Would it make sense to include the coverage data from their spec?

Also keep getting super large number from sto exterior coating, wondering if anyone have experience with this.
