PURPOSE: A body composition measuring apparatus and a biometric information managing system are provided to improve the inconvenience of the user by providing a body composition measurement result to the user with a user interface. CONSTITUTION: An electrode part(110) is contacted with a subject to measure a body composition of the subject and includes a hand electrode part in contact with a hand of the subject and a foot electrode part in contact with a foot of the subject. A display unit(120) displays a body composition measurement result. An input unit(130) receives a height as a single input element for measuring the body composition. An impedance measuring unit measures the impedance of a body using the electrode part. A weight measuring unit measures a weight of the subject.체성분 측정 장치 및 생체정보관리시스템이 개시된다. 체성분 측정 장치는 신장 값을 입력받고, 측정된 체중 값과 임피던스 값 그리고 입력된 신장 값을 이용하여 피측정자의 체성분 값을 측정한다.
