The unit of measure here is the kilogram. Here we have prepared RFQ with the quantity of 1.555 kg. As the price is Rs 10 per kg or unit, by setting rounding precision as 0.1 we can get the exact price for the product. Using these methods we can set a unit of measures in Odoo 14.
To enable the option in Odoo, one needs to go to the inventory application, and go for Configuration -> Settings. Under the Products section, one will find the option, Units of Measure, there you can tick the option-units of measure and save it.
