• ### How Many Balloons Does It Take To Float A Human? | The ...

Sep 06, 2008· So to calculate the lifting power of Helium, start with the weight of air in volume L. Since the Helium itself has weight, we need to use the difference in density between air and helium. Since the density of air is 1.2 kg/m3 and Helium is 0.1787 kg/m3, to lift a object of 1 pound (0.453kg), you need 0.453/(1.2-0.1787) m3 of helium, or 0.443 m3.
