Jubelio doesn’t use unit-to-unit conversions. You are required to create a separate SKU for each unit of goods sold and their variants. This is done so that the goods sold are in actual (original) form.
For example, you sell three fabrics 100 meters long with three different color variants. You have to cut the fabric to a specific size to catalog it. If you want to sell per 2 meters, then you have 50 stocks with three different variants.
