# Configure non-standard units of measure

Configure non-standard units of measure in the

Engineering Units Dictionary

. For example, express the number of pieces produced in one hour in beats per minute using non-standard units of measure.Non-standard units of measure have specific properties. where X is the input value, M is the slope, and Q is the intercept that calculates the Y output result.

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

- InProject view, right-clickModel,
- SelectNew > All > Engineering unit.
- SelectEngineering unit dictionary.
- Double-click the new dictionary.
- In the title bar ofMeasurementSystemMapthat opens in the center of the screen, select . A new row appears in the map table.
- In thePhysical dimensioncolumn, select the reference quantity for the non-standard unit of measure. For example, for the beats per minute, selectFrequency > Hertz.
- In theDisplay namecolumn, type the name of the unit of measure.
- In theDescriptioncolumn, type a description for the unit of measure.
**TIP:**NameandDescriptionare both translatable through theLocalizationDictionaryobject. - In theSlopecolumn, enter the conversion coefficient for the standard unit value. For example, enter 60 to calculate beats per minute.
- In theInterceptcolumn, 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.
