Where used§


Data fields§

This is the complete name for the unit of measure. Unlike most other Name attributes, this value is limited to 4 characters, such as each, mm, kg and ohms.
While this field can accept units of measure with Unicode characters (like cm² and ), keep in mind that older downstream software, like some manufacturing applications, may not know how to interpret these characters. You may want to test your other computer systems before using Unicode in your PDXpert data.
This gives the unit of measure more fully.
UoM category§
Use this dropdown list to select the appropriate category for the unit of measure. See the Units of Measure (category) collection help topic.
Ensure that the correct category is selected. You cannot change this value after the new member is saved.
Measurement locale§
You can specify whether a unit of measure is related to one of the principal regional measurement systems, or is globally applied.
Conversion constant§
This number represents the number of default units required to make the unit. That is, there are [conversion constant] x [default members] per [this member]. The default member is, by definition, equal to 1.0.
The question is: How many units of the default member do you need to equal this member?
Example: There are 100 centimeters in one meter. If the default member for the Length UoM Category is centimeter (conversion constant = 1), then the conversion constant for meter would equal 100. Conversely, if the meter member is the default (conversion constant = 1), then the conversion constant for centimeter would equal 0.01.

Keep poorly characterized unit types ("carton", "as needed", etc.) to a minimum, since they are not convertible to other compatible units on part lists.
