# Gas pressure forces in metal gas bottles looks too big for my layman's mind. Are my numbers wrong? [closed]

I am trying to understand how much force is acting on a gas bottle in a measurement that I can grasp. (Like on TV, size of stuff are often measured in 'football fields' or 'jumbo jets').

So I have a standart gas bottle which I want to fill with some gas, maybe compressed air.

And I have read somewhere in the forums that similar gas bottles can safely contain pressures of 125 psi; even number 375 psi is mentioned:

So when I use such bottle with 300 psi of compressed stuff I want see how much torment I put on my bottle. First I calculate area of bottle using this formula:

So I approximate 2600 square inches, and each inch is pressed with 300 pounds of force. That is 2600 x 300 = 780000 pounds!!! In metric wording: over 350 tones are interrogating integrity of this bottle. My car weighs only 0.8 tone. It is like stacking 430 of my cars on top of each other, or 6 Abrahams tanks to convince it to explode, and still this bottle wouldn't budge.

Are they really so strong? How?

Almost 400 tones!
