Helium Charts and Float time

The charts below will show you how many balloons a 242 helium tank can fill up,  average float times, and the capacity of the different sized balloons. If you have a different size helium tank use this formula to figure out how many balloons your tank can do.

( Tanks size in cubic ft) divided by (Cubic ft capacity of balloon) = How many balloons you can inflate

Example:

11″ balloon = .5 cubic ft

If you have a 242 helium tank

(242 cubic ft) divided by ( .5 cubic ft ) = 484

242 cubic ft tank= 484 11″ balloons.

  • Float times are based on indoors only. Outdoor balloons will not float as long as indoors.
  • Float times also vary depending on weather conditions and the altitude of where you are located.
