Aren't you confusing buoyancy and weight?
- thaumasiotes 10y agoWhat's weight? Mass is well-defined; you could call weight "the force of gravitational attraction between the object and the earth" or you could call it "the force acting upon the object, when at rest". Since we're talking about measuring weight, I was using the second one, which is easy to measure directly. Granted, I was also using the first sense when talking about the weight of the helium specifically. I guess in that sense my terminology could have been better.
