A more thorough explanation:

Definition: Scale tolerance refers to the acceptable range of variation in the weight or mass of the same item when measured on different scales.

For example, if a bag of apples is weighed on three different scales, the weight may vary slightly due to differences in calibration or other factors. Scale tolerance allows for a certain amount of variation within an acceptable range, so that the weight difference is not significant enough to affect the sale or use of the product.

Another example could be a shipment of goods that are weighed on different scales at different points in the supply chain. Scale tolerance ensures that the weight variation is within an acceptable range, so that the shipment is not rejected or delayed due to weight discrepancies.

Overall, scale tolerance is important in ensuring accuracy and consistency in weight measurements, while allowing for minor variations that do not impact the quality or value of the product.
