How can i find the density of the human body?

Answer 1

It is *about* 1 gm/cc, since people barely float in fresh water.

Your local bariatric medicine center may have a calibrated tank of water to use in determining overall percent body fat. This would also be usable to determine more exact density.

Generally, fat people will be less dense; muscular bony people more dense.

Answer 2

The most precise way to do it is to follow the equation, where

Density = mass of body/volume of body.

Mass you can measure with a set of scales, (but use kg).
Volume is a bit tricky. The mass of water displaced is equal to the volume the body takes up, but this is only because water has a density of 1000kg/m^3 (or 1 g/cm^3), and only handy if you can catch all the water you displace.

Volume is calculated by the height x width x breadth, (all measured in m, or your density will be in kg/cm^3) so make a few estimates and pow! There's your volume. Now divide your mass by your volume and there's your density.

Given that the human body is mostly water, you have a ballpark figure to aim for.

Answer 3

Put the human in a bath and find the amount of water displaced, this is the volume. Then use;

density = mass/volume

Answer 4

the only thing with using water displacement is that when incorporating the volume, you use the total volume of water displaced, not just the total volume of water. So when doing the water displacement, you need to have it in a container with markings on the side so you can see how much the water level increases when the mass of the human body is added.
