Aluminum Stool,True,49.00,25.00,Stockable Product,"Website Desicption",True,product.uom/20
Chair,True,89.00,40.00,Stockable Product,"<p style='color:red'>Website Desicption</p>",True,product.uom/product.product_uom_cm

Above is my csv file. When I validate the CSV is show the below error:

• No matching record found for external id 'product.uom/20' in field 'Unit of Measure' at row 2

  Get all possible values

• No matching record found for external id 'product.uom/product.product_uom_cm' in field 'Unit of Measure' at row 3

  Get all possible values

May I ask how to import product with Unit of Measure by using CSV?

Thank you
