Hello there, @judys.
Currently, It isn't possible to set a specific price to each u/m by using measurement in QuickBooks.
As my colleague mentioned above, that's the only way to set up a price for each unit of measure.

Please let me know how everything goes in the comment section below. I'll be here if should you need anything else. Have a great day.
