A weight scale includes weight measurement means, storage means for storing a weight measurement value along with a measurement day and time, determination means for determining whether a fluctuation range of the weight measurement value in the same day is within a predetermined reference range, and display means for displaying a percentage of days determined that the daily weight fluctuation is within the reference range. In this manner, a trend in weight change can be grasped even with the measurement of a relatively short period.
