Disclosed in the invention is a dual-purpose electronic scale comprising a carrying plate, a first precision weighing assembly for supporting the carrying plate, a second precision weighing assembly for supporting the carrying plate and the first precision weighing assembly, and a force guiding element for transmitting a pressure exerted on the element to the second precision weighing assembly. The force guiding element consists of a bearing plate with a bearing hole and pad and support elements; the bearing plate serves as a guiding and supporting part; and the bottom wall of the carrying plate serves as a guiding and pressing part. When carrying no object, the guiding and pressing part of the carrying plate is higher than the guiding and supporting part of the force guiding element; when carrying an object, the carrying plate presses the elastic support element down and thus moves down; after the force applied on the carrying plate reaches a certain degree, the guiding and pressing part presses the guiding and supporting part of the force guiding element. According to the invention, the provided electronic scale can be used both as an electronic weighing scale and an electronic kitchen scale; and when the weight of the carried object exceeds a maximum range of the kitchen electronic scale, the kitchen electronic scale can be protected from being damaged effectively.
