The real advantage to hydro static weighing is that it gives one of the most accurate measurements of body fat.
<u>Explanation:</u>
Hydro static weighing is a technique that is used to measure the fat of human body. The measurement uses the principle of Archimedes. The principle states that every body displaces an equal amount of water when it is immersed in a water.
It is based on the fact that the force called buoyant force that is exerted by water on the body that is immersed in water will be same as the weight of water that is being displaced by the body.Hence, hydro static weighing helps in the accurate determination of the body fat.
