A measuring apparatus and method for calculating height and weight of human subjects. A scale having a weight sensor is provided to sense the weight of a subject standing thereon. A sonar head is positioned stationary a predetermined distance above the scale sufficient to permit a subject to stand upright on the scale and below the sonar head. The sonar head has a sound wave emitter and a plurality of sound wave receptors. A data processing circuit is connected to the receptors and is activated by an operator and receives output measurement digital signals from the receptors and the scale. Further digital reference signals are received from the receptors without the subject standing on the scale. The data processing circuit is controlled by a software to calculate the weight and height of the subject. The apparatus and method also provides additional data on the subject, such as the body surface area, age and sex.
