# Unit of Measure Groups

Group: Inventory

[Open in the interactive reference](https://docs.api.lensing.ai/lensing/v1/groups/inventoryUnitOfMeasureGroups)

A unit of measure group is a set of units of measure that convert to one base unit of measure.

A group has a conversion line for each of its units of measure, giving the number of base units in one of that unit. The base unit's own line has a factor of 1. For example, a group based on 'EA' might have 'BOX' at 12 and 'PALLET' at 480.

Items are assigned to a group, and an item's inventory, sales, and purchase units must be units in that group.
