Configure non-standard units of measure

You can configure non-standard units of measure in the Engineering Units Dictionary. Using non-standard units of measure you can, for example, express the number of pieces produced in one hour in beats per minute.

Non-standard units of measure have specific properties. Slope is the conversion coefficient to convert the standard unit value to the non-standard unit. Intercept is the value to add to the referenced unit of measure. The conversion is performed using the linear expression  Y = M x X + Q where X is the input value, M is the slope, and Q is the intercept that calculates the Y output result

  1. In Project view, right-click Model.
  2. Select New > All > Engineering unit.
  3. Select Engineering unit dictionary.
  4. Double-click the new dictionary.
  5. In the title bar of MeasurementSystemMap that opens in the center of the screen, select Add.

    A new row appears in the map table.

  6. In the Physical dimension column, select the reference quantity for the non-standard unit of measure.

    For example, for the beats per minute, select Frequency > Hertz.

  7. In the Display name column, type the name of the unit of measure.
  8. In the Description column, type a description for the unit of measure.
    Tip: Name and Description are both translatable through the LocalizationDictionary object.
  9. In the Slope column, enter the conversion coefficient for the standard unit value.

    For example, enter 60 to calculate beats per minute.

  10. In the Intercept column, enter the value to add to the referenced unit of measure.

    For example, enter 0.

The resulting unit of measure appears in the Result column.
Tip:
An example non-standard unit of measure that expresses 1 Hz = 60 beats per minute, may contain these configured properties:
  • Physical quantity. Frequency.
  • Display name. BPM.
  • Slope. 60.
  • Intercept. 0.
