To select a base unit of measure to a UOM group:
- Select the unit of measurement that you have decided to assign as a base one
- Use the Set unit of measurement as base item of the context menu or the Document > Set unit of measurement as base main menu item
- A flag will appear next to the selected unit of measurement in the Base column. And the coefficients of already created units of measurement will change. The coefficients will be calculated regarding the new base unit of measure.
