formula

does anyone know the formula for tank volume relative to psi vs. cf

I have a program, if you give me the operating pressure,
rated tank volume, and current pressure in tank.
I'll tell you the current volume.
I do have the formula, I'll have to look it up. I'll post it later if someone don't beat me to it.

lets say lp 95 2250 jacked to 3000=cf?
lp 100 2650 3000=cf?

I'm getting ready to spend some money and want to make it count

The 95 volume comes out 126.66
The 100 comes out to 113.20

95 cft tank rated at 2,250 PSI pumped up to 3,000 PSI: 95 x (3000/2250) = 126.66 cft of gas.

100 cft tank rated at 2,650 PSI pumped up to 3,000 PSI: 100 x (3000/2650) = 113.21 cft of gas.

Formula: Rated CFT x (actual PSI/rated PSI) = actual CFT of gas

thanks guys
