A body fat determining device takes the form of a weight measuring device, and has two pairs of electrodes, a display, and setting buttons on the upper sides. Each of the electrode pairs comes into contact with one of the subject's sole when the subject stands on the device. The electrodes of the electrode pairs can form current paths with each other, and are also provided for measuring the impedance of the subject's body such that the impedance of the contact between the subject's soles and the electrodes is eliminated from calculation. In other words, the accuracy can't be affected by unwanted factors such as moistures, roughness, or area of the subject's skin in contact with the electrodes. The device can find data that are stored in the memory, and belong to the present subject for calculation according to the datum on weight; thus, every subject only has to input data about him at the first time he uses the device.
