I need some help...

I got a question. Say I have a 50/4500 air tank, I know the 50 is the circumference and the 4500 is the air capacity...? What is psi and am I right about the 4500 air capacity?

The first number is the overall internal size actually. It's the 'Cubic Inches' of space the tank actually holds. With a 50ci tank there are 50 cubic inches.
The 4500 is the pressure rating. So it's rated for 4500 pounds per square inch, psi. Same with a 3000 psi tank, it only is rated to take 3000 psi.
So with the 50/4500 tank you have 50 cubic inches and within 1 cubic inch holds 4500 psi.

Then why do people say they have 200 psi. But they have a 4500 tank?

Because that's the overall pressure left in the tank. The maximum fill is up to 4500 psi. As the air is used the pressure drops to 0 psi when the tank is empty.
