When scuba divers calculate their buoyancy with an aluminum cylinder it is essential for them to know the relative buoyancy characteristics of their chosen cylinder at full pressure capacity and also at their minimum reserve 500psi.

The al100 and some of the larger capacity high pressure tanks such as the hp117 and hp133 are also 8 inches in diameter although the hp120 is a 7 inch tank.

This is why simple units conversion of free capacity between imperial and metric cylinders is improper becoming more significant as the water volume or pressure increases particularly for manifolded cylinders aka doubles or twinsets xs scuba steel x7 100 faber dot us specifications.

It is kinda difficult to convert actual tank pressures into gas volume using the imperial measurements. Steel scuba tanks are denser than aluminum tanks meaning you have to be less concerned with buoyancy issues especially at the end of a dive.
