I have read several threads on the forum but none have a good solutions for handling multiple units of measure. Is there a way to manage multiple units of measure? For example, a product is sold by the EA (each), BX (box), and CS (case). The Product SKU is the same for each unit of measure but the box may be contain from 2 to n eaches. In addition, a case is 2 to n boxes. The ERP system they use simply calculates the quantity based on the conversion factor for the additional unit of measure.

Example Product: Widget

SKU = EA (each)
BX = 4 EA
CS = 16 EA

If the customer wants to buy 2 boxes, they are essentially buying 8 each of the Widget but should be sent 2 boxes.

Thanks in advance for any suggestions.
