Nice try, but we aren't talking about motives and goals. We are talking about what is measured by immersion.
It's really amusing to watch you people squirm.
Read a full description of what is done in the calculation of body fat. You need to calculate density, which is a ratio of volume to weight (or mass if you insist).
Immersion measures body volume.
Speaking of squirming, you can squirm and wiggle all you want but you were still wrong in post 763, 765, as in this one, that immersion does not measure weight.
Here’s a clue, there’s motive behind all measurements, unless you’re going to argue that people measure things just for kicks and grins.
For the last time, people aren’t interested in body volume, they’re interested in % of body fat MASS. Immersion is one way to find out such a thing.
If anyone’s squiriming it’s been you, losing this argument, arguing that gravity can somehow be talked about in terms of material, and that you can’t back up your absurd statements about metmom and the internet.
