A label manufacturer would choose the Component/Sub-assembly Manufacturing as the facility type, for which Kg is the default unit of measurement in Higg FEM 4.0. So facilities will be required to input their annual volume in kg. There is also an option of inputting the annual volume in piece/pair or SAM in this facility type if the facility chooses to enter. In this case, you can enter both kg and pieces/pairs. But please note that it would be easier to utilize one unit of measure to normalize data, especially when a facility has multiple size and material GSM items.
