Diving cylinder names.. confused.com!

[Daniel M. Thomas]

Hi divers!
I hear y'all talking about tanks calling them by names that i am not familiar with, "Faber 100's" , "alu 80's" stuff like that
Where i am from in the UK, we call tanks by their sizes in litres and that to me is easy to understand

Can anyone point me in the direction of somewhere i can learn the difference between the two and how i can know what means what. Talk to me about tanks in litres and its easy, i get, no probs..talk to me about ALU 80's and you've lost me... i know it's simple and i should get it by now, but for some reason i don't

Untangling cubic feet, litres, PSI, bar for scuba tanks and RMV / SAC calculations


But for your example (provided it's filled to the US rated 3000 psi aka 200(ish) bar and not overfilled) a aluminum 80 is an 11.1L tank.

Also keep in mind the US very rarely gets 300bar tanks. We normally max out at 3442 (with a rare 3500) psi ~ 237 bar.

This DGX article covers everything. It's a good read explaining the calculations and there's a quick reference table at the bottom.
