You brought water displacement up in a discussion of gravity. I don't know why you brought it up. It makes no sense. Archimedes discovered that water immersion allows

No, I pointed out that one can determine mass without gravity.

The reason fat analysis requires the particular methodology of immersion is that volume is needed for the formula.

Right, and generally fat is spoken of in terms of mass, not volume.

So how does your procedure calculate the fat content or percentage for people who don’t float?

I’m dying to hear how you weigh someone via immersion if they are too dense to float.
