Procedure

  1. In the module navigation menu, navigate to Units of Measure Conversions.
  2. Select the Manage Conversions tab.
  3. Select the unit group that you want to rename.
    Note: You can rename only the user-created unit groups.

Create a Units of Measure Conversion

You can add a new units of measure conversion to a unit group.

Before You Begin

You must have tenant admin permissions or specific permissions to access the Units of Measure Conversions page.

Procedure

  1. In the module navigation menu, navigate to Units of Measure Conversions.
  2. Select the Manage Conversions tab.
  3. Select the unit group for which you want to add a units of measure conversion.
    The color of the selected unit group name changes to blue.
  4. In the section for the selected unit group, select , and then select Add a new unit conversion .
    The Add New Unit Conversion window appears.
  5. As needed, enter values in the available fields.
    Field NameDescription
    DefaultIndicates whether the units of measure is set as default.

    You cannot modify this field. However, you can set a units of measure conversions as default in the Units of Measure Conversions page.

    From Unit AliasesDefines the different unit names for the units of measure for which you want to convert the value.

    The names are separated by commas (for example, kilometers, kms).

    From UnitDefines the units of measure for which you want to convert the value.

    For example, if you want to convert the input value from kilometers to miles, kilometers is the From unit of measure.

    Note:
    • The value in the From Unit field should be unique for each unit group. You cannot add the same From Unit field value that exists in another unit group.
    • Previously, the letter ‘g’ was used in Pressure to represent standard gravity unit and in Weight to represent gram unit. Now, the letters are differentiated by font: an Arial ‘g’ is used to represent standard gravity unit, and a Calibri ‘g’ is used to represent gram unit.
    To Unit AliasesDefines the different unit names for the units of measure to which the value is converted.

    The names are separated by commas (for example, miles, mi).

    To Unit Display NameDefines the units of measure to which the value will be converted.

    For example, if you want to convert the input value from kilometers to miles, miles is the To unit of measure.

    The selected name appears as a unit label for the converted value.

    Note: Previously, the letter ‘g’ was used in Pressure to represent standard gravity unit and in Weight to represent gram unit. Now, the letters are differentiated by font: an Arial ‘g’ is used to represent standard gravity unit, and a Calibri ‘g’ is used to represent gram unit.
    To System of MeasureDefines the system of measure of the To unit of measure to which the value will be converted.
    ExpressionDefines the mathematical formula that is used to convert the value.
    PrecisionDefines the number of digits that should appear after the decimal point of a value based on the following options:
    • None

      Does not change the converted value.

      If you do not select a precision value, by default, None is selected.

    • 0

      Considers only the digits before the decimal point and omits the digits after the decimal point.

      For example, if the value is 2.91 and a precision '0’ is selected, 2 is the resultant value.

    • 1 to 10

      Indicates the number of digits to be considered after the decimal point, respectively.

      Based on the specified precision, zeros are added at the end of the converted value to make the number of digits after the decimal point of the converted value match the precision selected. For example, if the value is 2.92 and a precision '4' is selected, then 2.9200 is the resultant value.

    RoundingDefines the type of approximation of a value based on the following options and the specified precision:
    • None

      Does not change the converted value.

      If you do not select a rounding value, by default, None is selected.

    • Ceiling

      Increases the value to the nearest number.

      For example, if the value is 2.926 and the precision is set to 2, the value will be increased to 2.93.

    • Floor

      Decreases the value to the nearest number.

      For example, if the value is 2.926 and the precision is set to 2, the value will be decreased to 2.92.

    DescriptionDescribes the units of measure conversion.
  6. Select Submit.

Results

The units of measure conversion is added. A appears next to it, indicating that the units of measure conversion is a user-created record.
Note: In Predix Essentials, when a System of Measure (SOM) is created and assigned to a user, and the user logs in, the same SOM (also known as UOM conversion set) will be available in the Units of Measure and Conversion Set page in Configuration Manager. However, user will have to manually create the unit of measure conversions for the new conversion set in the Units of Measure and Conversion Set page. For information on adding a units of measure conversion, see https://www.ge.com/digital/documentation/meridium/Help/V43100/IZTk4MzQ1NGYtOTE3Yi00YjI5LWE5ZTUtNWRhODQxNDE2Njc0.html#t_apm_units_of_measure_and_conversions_add_contents_uom_conversion_set.

Example

Example: A tenant admin creates a new SOM called Metric and creates a units of measure conversion such as Centimeter to Meter and then assigns it to UserA.

When the UserA logs in to Predix Essentials, Metric will be automatically created in the Units of Measure and Conversion Set page without the units of measure conversion. UserA must manually create the units of measure conversions such as Centimeter to Meter in the Units of Measure and Conversion Set page.

Note: This example does not apply to Predix Essentials.

Upload Units of Measure Conversions

You can upload multiple units of measure conversions using the template file.

Before You Begin

You must have tenant admin permissions or specific permissions to access the Units of Measure Conversions page.

Procedure

  1. In the module navigation menu, navigate to Units of Measure Conversions.
  2. Select the Upload Conversions tab.
    Note: You must add the units of measure conversions that you want to upload to the template file. To download the template file, select Download Template.
    While adding the units of measure conversions to the template file, you must ensure the following conditions are met:
    • None of the fields should be empty.
    • The order in which the fields are displayed should not be changed.
    • The From Unit value of a unit group must not be used in another unit group.
    • The To Unit and From Unit values should not have the same aliases.
    • The precision value should range from -1 to 10, where -1 retains the calculated value as-is.
    • The rounding value should be Floor, Ceiling, or None.
    • The units of measure conversions should be unique. Any replicated units of measure conversions will be discarded when the file is uploaded.
    • Only the system of measures that are available in the system should be assigned.
    • The To Unit Display value should be one of the To Unit values.
    The following table shows a sample data of the template file.
