> and 800 million cubic feet of helium
I don't understand why you'd measure the amount of a gas in volume units (e.g. cubic feet) given that any gas is "elastic" in volume, i.e. can take pretty much any volume depending on the pressure.

> Standard cubic foot (SCF) means the volume of gaseous helium occupying one cubic foot at a pressure of 14.7 psia and a temperature of 70 degrees Fahrenheit. One liter of liquid helium is equivalent to 26.63 scf of gaseous helium. One U.S. gallon of liquid helium is equivalent to 100.8 scf of gaseous helium. One pound of liquid helium is equivalent to 96.72 scf of gaseous helium. If BLM approves, you may use appropriate gaseous equivalents of volumes of helium mixtures different from these figures.
