How to setup unit of
measure in Odoo

2. INTRODUCTION
In some cases, handling products in different unit of measures is necessary.
For example, if you buy products in a bulk quantity then it is difficult to
mention the basic unit of measure on purchase. Suppose we are planning to
buy a 2ton of sugar. The base unit if measure of sugar is in Kg. Instead of
giving order of 2000kg we can give 2ton. Here I am taking this example and I
will show you how it works in Odoo inventory.gento is an open source e-
Commerce.

3. Merchant software that you can use to build an online show case of your
own, it was founded by eBay, and it is available as Enterprise and
Community Edition.
Before that we have to enable the different unit if measure. So, In the
Inventory application, go to Configuration Settings. In the Products
section, select Some products may be sold/purchased in different units of
measure (advanced), then click on Apply.

4. Go to Configuration - Configurations - Units Of Measure.
Create a unit Provide the name for the unit in the field unit of measure set
the category of unit of measure as the base unit (Weight). You can only
define a fact /ratio between two units if they share same category.

5. Category:
1. Reference unit for this measure category.
2. Smaller than the reference unit.
3. Bigger than the reference unit of measure.
In our case we taking Kg as base so configure it as follows.
So we are creating a UOM Kg with type as Reference unit for this measure
category.

6. Create another UOM as Ton with type as Bigger than the reference unit of
measure.
When we select the type we can now set bigger ration, how bigger the uom
than base UOM. 1Ton means 1000kgs.

7. Create another UOM as g with type as Smaller than the reference unit.
Now give the ratio 1kg = 1000grams

8. We are making the purchase order with the unit of measure Ton. Which
means sales is in Kg and purchase is in Ton.
After setting the UOMs we should select the UOM in product master. Set the
UOMs as follows:
1. Unit of measure is ‘Kg’
2. Purchase unit of measure is ‘Ton’

9. All internal transfers are expressed in the Unit of Measure.
