Scuba Tank / Paintball Tank Fill Calculator

This calculator will answer the always asked question, "How many fills can I get from a Scuba Tank?" The problem is - there is no single answer.. you will get a lot - but the pressure on each fill will drop. You can get a lot more fills at higher pressure if you cascade your scuba tanks. Check out this link for an explanation of tanks and fills.

To use this calculator, simply choose which size and pressure scuba tank you are using, along with what size paintball tank you have, and then choose what pressure you will refill at. Then click the calculate button and you can see what the pressure of your next 20 fills would be using either a single, dual, or 3 tank setup.
