# Units of measure (CS203100)

Last modified February 19, 2026

> This window displays the reference table of unit conversions for the units of measure (UoMs) used in Visma Net.


This topic provides information about the elements in this window in Visma Net, such as fields, field values, buttons, and check boxes.

This window displays the reference table of unit conversions for the units of measure
(UoMs) used in Visma Net. You can add new units of measure by specifying how they can be converted to
other units of measure available in the system.

For more information about units of measure, see: [About units of measure and conversions](https://docs.vismasoftware.no/visma-net-erp/help/inventory/manage-inventory-defaults/about-units-of-measure-and-conversions/index.md).

## What to do from this window

+ [Define weight UoMs](https://docs.vismasoftware.no/visma-net-erp/help/inventory/manage-inventory-defaults/define-weight-uoms/index.md)

## The table

This table displays the relationships among the units of measure defined in the system.
Each
line in the table defines a rule used to perform a conversion from one unit of
measure to another.
When you add a new unit, specify its conversion first to itself
and then to other units.
Units from this table will appear on the list of UoMs used
to define item classes.
