Air Fill Calculations

Hey All,
I am trying to figure out if it is going to be worth it for me to get my old SCUBA tanks hydro'd or buy a new 4500psi tank. I have a pair of HP100's. These are steel 3500psi 100cf tanks with DIN valves. I would be filling a 490cc tank. I am wondering how many fills I could get using one tank to fill and the other to top off. Assuming filling to 3000psi and refilling @ 2000psi.
Anyone have any formula's they would like to share?

Using the figures you provided each tank would give you 12 fills.
A 88 cf 4500 psi carbon fiber tank would give you 25 fills.
Hope this helps..

There are two fill calculators on the internet I use:
For single tanks....

For cascade systems....
