Display sets for units of measure

An administrator can create a unit of measure display set so that units are displayed using the preferred system, rather than the as-authored unit.

Base units

The unit management system (UMS) defines many values for each unit of measure (UoM): whether it is metric or non-metric, the type of unit, whether it is a base unit, and if not, the conversion factor from the base unit. This information allows Parameter Management in Teamcenter to convert between the various units (for example, 1 inch = 2.54 centimeters).

There must be one base unit for each system of measurement (metric and non-metric). Within a measurement system, all other units are based on the base units. To enable conversion between metric and non-metric, all conversion values must be based on just one of the base units.

The unit management system provides a long list of predefined units of measure, both metric and non-metric, with many units defined for each unit type (e.g. length). Three display sets are provided to organize these units for the user: Metric, Metric (SI), and Non-Metric.

Example preferred units per display set:

Unit type	Metric	Metric (SI)	Non-Metric
Length	m	m	ft
Area	mm²	m²	ft²
Capacitance	F	mF	µF
Temperature	°C	°C	°F

Custom display set

You can define additional display unit sets for your users.

Note: When working with the unit of measure definitions, unit types are called Quantity.

UMS stores all unit definitions using the Classification system. The attributes of the class align with the columns of the CSV file that is imported. To create a custom display set, you must create a new column in the CSV file.
