I think metric is far easier to visualise. Every ten metres of depth is another bar of pressure. So the surface is 1 bar, 10 metres is 2 bar and so on.
The same with cylinder fills, each extra bar is a tankfull of air. So a 10 litre cylinder filles to 200 bar contains 2,000 litres of air. It is just so easy.
To us Brits it is quaint that some former colonies have hung on to our "Imperial" measures when we ditched them ages ago. Metric is based on science and logic, Imperial is descended from strange practices in medieval English villages. Measures such as a Gill, a Perch, a Rod and a Link are just history.
