A method for counting the number of articles or goods of the same kind using a weighing machine which comprises a step of measuring an average or mean weight of sample articles, a step of measuring a weight of all articles to be counted and a step of calculating the number of the all articles by dividing the measured weight by the mean weight. Said step of measuring the mean weight includes a step of measuring a temporary mean weight a1 of a known small number of articles P1, a step of adding any unknown number of articles P2, a step of measuring a weight W1 of these articles P1 plus P2, a step of calculating the number N1 of the articles by rounding off a quotient obtained by dividing the weight W1 by the temporary mean weight a1 and a step of calculating a standard mean weight a2 by dividing said measured weight W1 by said calculated number N1. |
