Thanks for the clarification.

But the argument started over a claim that immersion was used to measure weight, mass, and body fat. My first response — still correct after all these years — was that immersion measures volume.

You can measure the weight of an object by calculating the weight of the water displaced by a floating object, but as a practical matter it makes no sense to do this with human bodies.

The medical procedure for determining body fat uses displacement to measure body volume. Volume is an essential factor in the equation. Tpanther has consistently denied that volume is of any interest and he/she is wrong. Simple as that.

Even if you use displacement to measure weight, as with ships, you are measuring volume and calculating weight.

It is used in calculating body fat PERCENTAGE. And body fat is ultimately talked about in terms of MASS, not volume. You have to actually acknowledge each step in the procedure to understand this though.

Step one.

Volume is an essential factor in the equation.

Strawman.

You either have a serious reading comprehension problem...or you're a dishonest liar. I've consistently pointed out that volume is not what people are looking for when they put people into tanks to measure their body fat PERCENTAGE. Which is completely different than "denying that volume is of any interest". Are you capable of underatanding this js?

I also pointed out that I was a hospice nurse with a wife and kids...(and prior Air Force in other posts)...so it would stand to reason to virtually anyone that I'm a he.

Metmom said gravity wasn't material, but you mucked that up and butchered that beyond all comprehension too.

You should seriously get that looked into!

Any other science gurus want to defend tpanther and metmom?

Let's see...so far it's you against Swordmaker, kevmo, tpanther, metmom, well frankly, I've lost count...!!!!
