D b = Density of the body; M a = "Mass in air" (i.e. dry weight); M w = "Mass in water" (i.e. underwater weight); D w = Density of water (based on water temperature); RV = Residual volume (the unfilled space enclosed by the body- e.g. volume of air in the lungs + respiratory passages after a maximum exhalation).
Excess or reduced body weight is regarded as an indicator of determining a person's health, with body volume measurement providing an extra dimension by calculating the distribution of body weight. Average adult human weight varies by continent, from about 60 kg (130 lb) in Asia and Africa to about 80 kg (180 lb) in North America, with men on ...
Prior to the adoption of DXA, the most accurate method of estimating body fat percentage was to measure that person's average density (total mass divided by total volume) and apply a formula to convert that to body fat percentage. Since fat tissue has a lower density than muscles and bones, it is possible to estimate the fat content.
To calculate BMI, divide a person’s weight in kilograms by their height in meters squared. Translated into imperial, that’s a person’s weight in pounds divided by their height in inches ...

The average body weight of women in America has been steadily increasing over the past few decades. According to national surveys, about 42 percent of U.S. women have obesity and an additional 27 ...
A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).
