A little help needed on 4500 psi tank

Thanks. the AOA doesn't convert from CI to CF. Im going to keep researching it. I have googled it and the answers don't make sense. I got this tank as a package deal from airgun depot. I didn't have the extra money to piece it out and get the bigger tank right now. But this will work well for my hunting trips while I wait for my compressor to come in. Thanks for everyones help. If i figure it out I will post the answer.

Ok. GQ you are right. But this has been driving me crazy and I got the same answer. But that makes no sense to me. So I google weird questions and I found a search answer that brought me to and old yellow forum airgun site. The post was from Jock Elliot. All he said was you have to use the number (1728) to convert it. So I went to the site listed in the post up top and kept working it till it made sense. The answer is 14.2997916667 cubic feet. Thanks for everyones help.
So put in approx cubic foot into converter to cubic inches. I put 14 cubic feet which equals 24192 cubic inches. Then I divided 24192 by 1728 and got 14.299
Sorry so boring but it might help and now i can go back to sleep. lol
