A weighing method, comprising the following: - providing a weighing unit (402; 800), - picking up an object to be weighed on the weighing unit, - acquiring weight information, - determining a derived weight value and a quality value for the derived weight value by evaluating a predeterminable quantity of the weight information, - depending on the quality value, specifying that the derived weight value is a valid weight value, and - if there is a valid weight value, loading the weighing unit (402; 800) with a new object, wherein the derived weight value is determined as an average or moving average of a predeterminable quantity N of weight information, and the quality value is determined as a variance or standard deviation of the N weight information, from which the derived weight value has been produced, - wherein a system having at least two weighing units (802; 804) is provided, wherein the weighing units each comprise at least one weighing cell (806; 808) and a weighing pan, and wherein the weighing cells of each of the weighing units are arranged cascaded in the direction of gravity such that the total weight of the first weighing unit and the weight of at least one further weighing pan of the at least one second weighing unit loads the weighing cell of the at least one second weighing unit as a pre-load, the weighing pan of the first weighing unit is arranged in front of the weighing pan of the second weighing unit, which is situated in the transport direction, and the at least two weighing units are communicatively connected to at least one electronic evaluation unit, and - wherein derived weight values and quality values are determined for at least two weighing units, preferably independently for each of the at least two weighing units, and if there is a valid weight value, the system is loaded with a new object, and - wherein an object weight is derived from at least one part of the valid weight values in that a provisional object weight is derived in each case from at least one part of the valid weight values which have been determined for a weighing unit, and the object weight is derived from at least one part of the provisional object weights, preferably in that an average is produced from the at least one part of the provisional object weights. - providing a weighing unit (402; 800), - picking up an object to be weighed on the weighing unit, - acquiring weight information, - determining a derived weight value and a quality value for the derived weight value by evaluating a predeterminable quantity of the weight information, - depending on the quality value, specifying that the derived weight value is a valid weight value, and - if there is a valid weight value, loading the weighing unit (402; 800) with a new object, wherein the derived weight value is determined as an average or moving average of a predeterminable quantity N of weight information, and the quality value is determined as a variance or standard deviation of the N weight information, from which the derived weight value has been produced, - wherein a system having at least two weighing units (802; 804) is provided, wherein the weighing units each comprise at least one weighing cell (806; 808) and a weighing pan, and wherein the weighing cells of each of the weighing units are arranged cascaded in the direction of gravity such that the total weight of the first weighing unit and the weight of at least one further weighing pan of the at least one second weighing unit loads the weighing cell of the at least one second weighing unit as a pre-load, the weighing pan of the first weighing unit is arranged in front of the weighing pan of the second weighing unit, which is situated in the transport direction, and the at least two weighing units are communicatively connected to at least one electronic evaluation unit, and - wherein derived weight values and quality values are determined for at least two weighing units, preferably independently for each of the at least two weighing units, and if there is a valid weight value, the system is loaded with a new object, and - wherein an object weight is derived from at least one part of the valid weight values in that a provisional object weight is derived in each case from at least one part of the valid weight values which have been determined for a weighing unit, and the object weight is derived from at least one part of the provisional object weights, preferably in that an average is produced from the at least one part of the provisional object weights.
