1. A weighing apparatus comprising:
a transport unit configured to transport an article;
a weighing unit connected to the transport unit, the weighing unit being configured to output an original signal related to a weight; and
a weighing control unit configured to output a weighing value of the article by processing the original signal,
wherein the weighing control unit is configured:
to determine whether or not to adjust a zero point on the basis of a determination signal obtained by applying a first filter to the original signal;
to generate an adjustment signal obtained by applying a second filter having more stages than the first filter to the original signal or the determination signal in a case where the weighing control unit determines that the zero point is to be adjusted; and
to perform adjustment of the zero point on the basis of the adjustment signal.
