Odoo – Managing Multiple Unit of Measures (UOM’s)

Dear Readers,

Today we will see how to mange Multiple Unit of Measures in Odoo.

We have to consider 3 things while working with different UoM’s.

  1. UoM Category
  2. Type, and
  3. Ratio

The UoM Category should always be the same between corresponding UoM’s. Here we take example of UoM which belongs to Category Weight.

  • Ton
  • Kilo Gram and
  • Gram

Units of Measure(1)Here, as we want to manage and stock the product Grain in Kilo Gram, so we set Type as Reference Unit of Measure for this category. And as the UoM Ton is bigger than Kilo Gram, so following option has to be selected for the Type with appropriate Ratio.

Units of Measure(2)And same for the UoM Gram with respect to UoM Kilo Gram.

Units of Measure(3)So once UoM’s are configured, we plan to purchase the product in Ton’s, sale in Grams and maintain in Kilo Gram within warehouse. So we have to configure the product as depicted in following images.

Products(1) Products(2)Products(3)So lets purchase the product, once you will select the product system will automatically propose UoM in Ton with converted pricing.

Requests for QuotationEven the incoming shipment will be in Ton, though while receiving the system will convert into Kilo Gram as we have configured it as a Default UoM.

TransfersSo once received, lets check the stock of that product.                                               1 Ton = 1000 Kilo Gram as per UoM configuration.

Products kanbanThe same thing will be applied while selling the product, though the system will not automatically propose Gram in Unit of Measure field, but it will in UoS, so we have to change Gram in UoM and the system will convert the Unit Price of the product accordingly.

Sales OrdersSo, hope this article helps you in getting insights on different Unit of Measures.

Thanks.                                                                                                                                 Bharat

  1. I have created a secondary UoM from the reference UoM of Units, to feet. But when I try to select the “Units”-reference UoM in purple dropdown list of the SO and select “feet”-secondary, it instantly gets changed back to Units and we are thus unable to create the SO with feet instead of Units. Why does this happen?
