Unit of Measure Attributes
The unit of measure attribute allows you to enter numerical measurement values for measured items. Six unit families are available out-of-the-box:
• Length
• Area
• Volume
• Liquid volume
• Dry volume
• Mass
You can display multiple units of measure for a single attribute. For example, you can display both inches and centimeters.
The system automatically converts any entered value into any additional units of measure. For example, if you create a unit of measure attribute using both pounds and kilograms, the system automatically converts any value entered for pounds and displays it as the kilogram value.
To define a unit of measure attribute, you must complete the Unit Family, Displayable Units, and Displayed Digits fields.
• In the Unit Family field, enter one of the following:
◦ si.Length
◦ si.Area
◦ si.Volume
◦ si.LiquidVolume
◦ si.DryVolume
◦ si.Mass
• In the Displayable Units field, enter one or more of the following values corresponding to a given unit family, separated by the multi-character delimiter |~*~|:
◦ si.Length—km, m, dm, cm, mm, mi, yd, ft, in
◦ si.Area—km, m, dm, cm, mm, in, ft, yd, mi
◦ si.Volume—m, dm, cm, mm, l, yd, ft, in
◦ si.LiquidVolume—l, oz, pt, qt, gal, br
◦ si.DryVolume—m, l, yd, ft, in, pt, qt
◦ si.Mass—mton, kg, g, lton, ston, pd, oz
• In the Displayed Digits field, enter one or more of the above display units followed by numeric digits to display, separated by the multi-character delimiter |~*~|.
For example, to display centimeters with two decimal points, millimeters with three decimal points, and inches with one decimal point, enter the following values:
• Unit Family: si.Length
• Displayable Units: cm|~*~|mm|~*~|in
• Displayed Digits: cm.2|~*~|mm.3|~*~|in.1
This table lists the unit families and displayable units for the unit of measure attribute.
