Hydrogen and helium are the most commonly used lift gases. Although helium is twice as heavy as (diatomic) hydrogen, they are both so much lighter than air that this difference is inconsequential. Hydrogen has about 8% more buoyancy than helium . Both provide about 9.8 N of lift (the force to lift 1 kg) per cubic meter of gas at room temperature and sea level pressure. Helium is preferred because it is not combustible.
