Good afternoon, @Yogi. 

Welcome back to the Community! 

I can see how beneficial this could be for your business. However, you'll need to add this information into the description box. QuickBooks doesn't have a built in unit of measure for tracking inventory. 

We recommend submitting feedback to our Product Developers so they can consider adding this as a new feature in QBO. 

Feel free to come back if you have any other concerns. I'm only a post away if you need be. Have a wonderful day!
