And for those of you who can't find your tank on there or don't want to haul a chart around.
tank size (at rated pressure in cuft)/rated pressure (psi) = "volume factor"
ie 80/3000 = 0.026
so...if you have a rated 80 cuft tank with 2300 psi
psi x "volume factor" = cuft of gas
2300 x 0.026 = 61.3 cuft of gas
Multiply by 2 if you are using doubles
i.e. double 119's rated at 3442 fill pressure with 4100 psi in them
119/3442 = 0.0345
4100 x 0.0345 = 141.7
141.7 x 2 (doubles) = 283.4 cuft of gas
