User Guide for Magento 2 Unit of Measurement (UOM)

Magento 2 Unit of Measurement (UOM) module allows store owners to sell products using different measurement units. These units include kilograms, grams, liters, meters, and more.

Moreover, the UOM Extension calculates prices automatically based on the selected unit.

It also tracks inventory using base units. As a result, store owners can manage stock more accurately.
