Conversion cubic to liters

[N² - O² diver]

I'm used to metric and i have not learned any different during my divemaster course in Europe / Belgium.

Could anyone give my a list to compare those differents to scuba divetanks ?

Like 10, 12, and 15 L

Maybe also the possibility to give these in a easy formula so i could explain these in the near future.

many thanks.

[300bar]

What I learned sofar,is that those handicapt with the imperial system don't have a clue either.
They messure the actual amount of AIR in cubc feet.
But besides having differenr tank sizes,they also seem to have Low pressure and High pressure tanks

The pressures they than quote don't come close to what we think is normal.

LP tanks seem to be 2400psi or 163 bar.Thats what I call an empty tank.
HP tanks seem to be 3000psi or 204 bar.Thats what we call a POOR fill

But it seems to go for all sizes of tanks.
I must admit,I still don't have a clue on this.
80 cubic/feet is a 11.1 Liter to us,but the same size tank in LP or HP seems to make a differance

232 or even 300+ bar are, or atleast seem to be exeptions.

Lot of "seems"in this post.
