How Much Air Is In A Scuba Diving Tank?

How much air can a scuba diving tank hold?

Hi,

Thanks for getting in touch. For the purposes of this discussion, I am going to assume we are talking about the average sized scuba tank filled to the standard 3,000 psi (pounds of pressure per square inch).

A scuba tank is filled with compressed air. The average sized scuba tanks holds about 80 cubic feet of air at 3,000 psi.

For comparison purposes, at sea level 80 cubic feet of air is usually described as being the size of a telephone booth. It will weigh about 6.5 pounds.

The air is then compressed to fit into the scuba tank. If you are interested, it is compressed over 200x to fit into the tank (3,000 psi/14.7 psi (which is the pressure at sea level) = 204).

Hope this is what you are looking for. Let me know if you need more info.
