In the general catalog settings, you can enable the display of measurement units for products.
Note: this option is available starting from the Standard plan.
To enable:
Go to Settings → General Settings.
In the Products block, check the Units box.
Click Save.
After that, in the product properties, in the Main info block, a new field Units with a list of values will appear.
The values of this field are stored in the Products → Attribute values list → Units list, to which several values that are used most often have already been added.
You can add unit values to products in bulk using an import file or when updating products through the API.
Displaying units on the website
Units of measurement will be displayed in the price block on the product page and in the mini-card.
Also, the unit of measurement is displayed in the counter for adding items to the cart and in the minimum number of units for ordering info.
