To access the UOMs list, go to Purchasing > See also > UOMs.

Various UOMs in the application are used to quantify assets.

Your company may need to use multiple UOMs for the same items if the same product purchased from different suppliers may is packed differently, of if the company purchases the item from suppliers in larger packs than
it sells them to customers. Alternatively, your company may consider different packings of the same item as different items -- this depends on the item as well as the company policies.

Multiple UOMs can be used for items if the Multiple UOMs per Item option is selected on the Administration > Settings > Purchasing and Warehouses form.

You can use FirstBIT ERP system for accounting in different units of measure. By default the system calculates weight in kilograms, length in meters and time in hours but all these units of measure can be changed. To edit the units of measure, enable the ‘Item accounting in different units of measure’ option in the ‘Purchases’ section. To learn more about the section settings, see par. Settings for the 'Purchases' section. Then add the required units of measure in the UOM Classifier.

To access the UOM Classifier, go to the ‘Purchasing’ section (see figure below).

The most frequently used units of measure are preset in the system. The easiest way to add units of measure is through the classifier integrated in the UOM Classifier. The classifier contains all known units of measure and their common abbreviations. To access it, press the Command Pick from classifier button on the toolbar above the list. In the displayed window (see figure below) check the units that you would like to add. Then press the ‘OK’ button.
