It allows you to convert between different Purchasing Units of Measure while maintaining a constant consumption UoM. ## Things to know - The Unit of Measure (UoM) can be configured on an individual item level. For example, wire or pipe can have a UoM. Serialized equipment, such as water and heaters, can't have UoM because they are handled individually. - Calculations for replenishment of the items with UoM are based on the UoM enabled on the inventory template assigned to the inventory location. > [!NOTE] > **Note:** ServiceTitan accepts only whole numbers for replenishment. ## Key workflows ### Activate the unit of measure for items Depending on whether or not an item has pending or completed transactions, there are multiple methods to activate the unit of measure for items: - [Activate the unit of measure for new items](/construction/docs/activate-the-unit-of-measure-for-new-items) - [Activate the unit of measure for items with pending transactions](/construction/docs/activate-the-unit-of-measure-for-items-with-pending-transactions) - [Activate units of measure for items with current stock levels and completed transactions](/v1/docs/activate-uom-for-items-with-current-levels-and-completed-txn) ### Set up a new unit of measure When you set up different units of measure for one item, you can use them during purchasing, transfers, and adjustments.
