OK,<br>
I concur with Cliff. I divided the 1500psi by 14.7 to get the number<br>
of atmospheres, then x that x 10.7 ( number of cubic feet) then x .0807<br>
(weight per cubic ft.)<br>

How can the air in a 10.7 cu ft tank weigh almost 85 lbs? I could believe .848 lbs...best check your decimal point...?Al Secor<br>

Hank,air weighs .0807 lbs per cubic foot approximately, depending on temperature.So if you have an 80 cubic foot scuba tank the air weight full is 6.45 lb.A scuba tank is 80 cubic ft at 3000 psi. If you halve the pressure you halvethe amount of air & weight. In other words, if you double the pressure youdouble the weight for a given volume.Let us know what you are trying to calculate if this doesn't help.Alan<br>
