In some industry sectors (for example, diary/meat, pharmaceutical, chemical, steel, or paper industry sectors), the composition or attributes of products vary to some degree. Therefore, you cannot use a fixed conversion factor to convert quantities of these products into various units of measure. Instead, each batch has to be given an individual conversion factor.
The weights can vary from piece to piece, either due to biological variations or because of weight loss during storage. This variability should not be lost by using fixed conversion factors, because this would mean that many business processes would be based on incorrect values.
