A unit of measurement (UoM) is the unit in which an item is counted, for example Nos, Box, Strip or Bottle. The same list also holds laboratory and vital-sign units, so each unit has a UoM Type. Units of type Inventory UOM are the ones you pick later for item categories, items and store dimensions.
