By default, all the products you enter in to Odoo use the same unit of measure, units. Often however you will find a need to purchase and sell products in alternate unit of measure. Silkworm has some products they purchase which come in cases. For example, they may need to purchase cases of coffee mugs they will sell as individual units in their retail stores.  Let’s see how we can configure Odoo to handle complex units of measures.

You turn on complex unit of measures by going to the Sales menu, then under Configuration choosing Settings.

On the far right you have the option Units of Measure. Check this option to allow multiple units of measure in Odoo. Click Save to confirm the change.
