Lift of balloon

  1. The volume of a sphere is 4/3 * pi * r3, where r is the radius of the balloon.
  2. One cubic foot of helium will lift about 28.2 grams, so multiply the volume of the balloon by 28.2.
  3. Divide by 448 -- the number of grams in a pound -- to determine the number of pounds it can lift.
