WebFor more accurate measurements of body fat, the use of instruments such as bioelectric impedance analysis or hydrostatic density testing is necessary. Fat mass (FM) formula: FM = BF × Weight Lean Mass (LM) formula: LM = Weight - FM BMI Method: Another method for calculating an estimate of body fat percentage uses BMI. WebA person’s mass happens to be 70 kg, while the gravity on Earth is 9.8 m/s 2. Find out the weight of this person? A1 In order to determine the formula of weight, one has to apply the weight formula. Here m = 70 kg and g = 9.8 m/s 2. W = mg. W = 70 × 9.8. W = 637 Nw. Hence, the weight of the person is 637 Nw.
