FIELD: medicine.
SUBSTANCE: group of inventions refers to medicine. A device comprises: a measuring device, a calculation device and an input device. Implementing the method involves extracting the living body information measured by the measuring device. The input device is used to accept the biological component information measured by the other device together with the date and time information. That is followed by determining if the biological component information is actual. If the biological component information is stated to be actual, the calculation device is used to calculate the biological information by formula: f(ρ)=a2·1/ρ+b2·W+c2·S+d2·L+e2. If the biological component information is stated to be inactive, the calculation procedure follows formula: f(ρ)=a1·1/ρ+b1·W+c1. Herewith, a1-c1, a2-e2 are the pre-set constants, ρ is a living body's specific resistance, S is a body part cross-section, L is a body part length, W is a living body weight.
EFFECT: group of inventions enables providing the more accurate body composition measurement by using the data extracted by the other devices.
