As mentioned before, Ergonode comes with a number of predefined units (based on the SI model) but you can also create your own at will, for example if your store measures products by boxes, cases, bags, etc. you can set those units up easily.
In order to do that, from within “Settings” navigate to the “Units” tab, click on the “New Unit” button and on the popup window that will be displayed give your unit a name and a symbol. Both need to be unique.
Once done, click “Create” and you’re finished.
Keep in mind, that the Unit attribute that uses these system units is numerical only, no other values can be entered.
