Weighing scale that automatically switches between a display mode or a communications mode based on whether communications is established with another scale

A weighing scale comprising:

• a platform for loading an object to be weighed;
• a weight measurer for measuring a weight of the object to be weighed when the object is loaded on the platform, to output weight data representing the measured weight;
• a display unit for displaying, as a measurement result, the weight represented by the weight data output by the weight measurer;
• a communication unit for transmitting the weight data to another weighing scale and for receiving weight data from the another weighing scale;
• a determiner that determines whether the weighing scale is capable of communicating with the another weighing scale via the communication unit;
• and
• a controller that controls the display unit to display the weight represented by the weight data output by the weight measurer in a case in which a result of the determination by the determiner indicates that the weighing scale is not capable of communicating with the another weighing scale, and that transmits the weight data to, or receives from, the another weighing scale in a case in which a result of the determination by the determiner indicates that the weighing scale is capable of communicating with the another weighing scale.
