Can I Change the UOM of the Items When Transferring Inventory between Warehouses?

If you are using the Transfer Journal to process the transfer, you have the option on the Item Journal Lines to select the UOM that you want the inventory to be converted to. 

If you are using the Transfer Orders, you can create a Put-away to convert inventory into different UOMs after you receive it into the destination warehouse. You can also create a Breakbulk Whse Activity to change the UOMs.
