My fill pressure for CNG is lower than my scuba tanks, so I am 100% sure a tank that would physically be a 60 cubic foot scuba tank is not holding more than 60 cubic feet of gas. You can figure it out for sure here: http://www.divebuddy.com/calculator/tankvolume.aspx Btw - with 2$ refills, I felt fine topping off to 2000 PSI instead of trying to cram the last bit in there.

You also need to know the compressed gas pressure, and apply the Charles and Boyle ideal gas laws to figure out an approximation. The rated volumes are for the amount of gas the cylinder contains at the nominal fill pressure, when expanded to standard temperature and pressure. (basically sea level and room temperature) Steve _______________________________________________ Thanks everyone for supporting this list with your contributions.
