Such various as hydrometry method, kalium method and under water weighing method (UW method) have been used in order to measure body composition. Although UW method is considered as the most reliable method, but needs a large experimental preparations, more simplified methods as skinfolds caliper method or ultrasonic waves method (USW method) are frequently utilized to measure fat content and lean body mass.
　This study was preparing the formulae for the prediction of body density by means of USW method for adult males and females basing upon our measurement of subcutaneous fat tissue thickness by B-mode* USW to know the objectivity and suitability of USW superior to skinfold caliper method.
　The formulae devided from this study follows;
　　For male D =1.0885-0.00098X
　　For female D=1.0815-0.00181X
　　X indicating the thickness of triceps and subscapula.
