Question

Quizplus · Accepted Answer

Hydrostatic weighing is based on the principle that body density is greater than the density of water. A person is weighed underwater, and the difference between the weight on land and underwater is used to calculate body volume. Body volume and body weight are used to calculate body density, which is then used to predict percent body fat.
