Scuba Tank Sizes Metric Imperial

Most primary tanks aluminum or steel are the common diameter of 7 inches.

Scuba tank sizes metric imperial.

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. A liter is slightly more than a us quart slightly less than a british one. 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. Smaller than an aluminum tank of the same capacity a steel scuba tank is a more compact air supply solution a fact that becomes doubly important for twin tank setups.

5 imperial gallons equal just over 6 us gallons. Liters to us gallons. Submersible systems spare air 6 0 cu. Water volume 12 9 l 28 32 l 1 ft 3.

Imperial gallons to liters. 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. 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. Many dive gauges sold in the us and canada use imperial measurements.

Tank pressure is represented in psi or pounds per square inch with 3 000 being a standard full point. An 80cf tank holds 80 cf when it s full to its rated pressure. Us gallons to liters. Kim definitely understands as far as i can tell.

The information is believed to be accurate but is not guaranteed. An 80cf tank with a rated pressure of 3000 psi will have a larger internal volume than an 80 cf tank rated to 3500 psi.

The information below was compiled from a variety of sources including luxfer pressed steel tank catalina and oms.

It is kinda difficult to convert actual tank pressures into gas volume using the imperial measurements.
