What I was trying to evidence was not metric vs. imperial, only about "visualizing" the whole stuff.
A Pascal by itself is not easy to visualize, a number of kg on a square meter (or for those used to it a number of pounds on a square foot) are IMHO easy to imagine, the 500 kg/m2 we were talking about can be visualized as 5-6 people standing one close to another or as a tank 1 m x 1 m filled with 50 cm of water.
As a side note, there is no conversion between kg and kgf, they are essentially the same thing, the 9.81 is already included, and it comes into play when you start using the (BTW proper SI) Newton:
