The invention discloses a four channel measurement electronic scale and a measurement method. The four channel measurement electronic scale comprises a housing, sensors on four corners of the housing, a signal amplification function unit, an AD conversion function unit, a central control unit, a data storage unit, and a display unit; the four sensors on four corners of the housing are connected to four measurement half-bridge modules; four half bridges constitute three groups of full bridges and one group of false full bridges; the four half bridges constitute three groups of the full bridges and one group of false full bridges to perform ADC measurement; the four ADC digital quantities are converted to weights; and the sensitive value K of each sensor is obtained. The sensitivity value K of each sensor can be calculated, the measurement data obtained by each channel can be more accurate, and the device can measure more accurately compared with the traditional human body electronic scale.
