What is Unit of Measure (UoM)?

A standardized measurement unit assigned to numerical product attributes such as size, weight, or volume. In PIM, UoMs ensure accuracy and consistency when importing, enriching, or syndicating product data across channels. They allow flexible value representation—such as cm vs. mm—while maintaining compatibility with standards.

Units make numeric values interpretable and determine whether conversions are valid. For example, an autonomous product data operation could take fixture dimensions reported in inches, convert them using the approved rule to the target millimeter unit, and retain source measurements and conversion precision.
