thank you Fiat Lux,

I am using QuickBooks Pro, when come to set the inventory item, i dont find any to set UOM (Unit of Measurement) for Stock in QuickBooks eg. kg, grams. litres, for Building of Material (BOM) - purposes)?

Why I want to set this UOM? it is because of cooking virtually purpose by using BOM eg. 1 bought 1kg chicken breast, but i only use 200 grams. How to set it in QBO?
