About Changing Parameter Units
You can change the units of a parameter if access to that parameter is not locked. To change the units of a newly created parameter, select the required units from the Units list for the same type of measure. For example, you can change cm to ft. Use the Changing Parameter Units dialog box to specify if you want to convert or interpret the parameter value. Interpret Value is the default.

When changing the unit of a parameter, click the In the future, do not show this dialog check box in the Changing Parameter Units dialog box if you do not want the dialog box to open again in that session of parameter modification.

You can specify the general rule for handling parameter values by selecting one of the following options in the Changing Parameter Units dialog box.
• Convert Value—Change the parameter unit and scale the parameter value automatically.
• Interpret Value—Change the parameter unit without scaling the value.
Effect of Changing the Model System of Units
Changing the model system of units affects system, application, and user-defined parameters that use model units. When you change the system of units, parameter values are not scaled automatically.
You can specify the general rule for handling parameter values by selecting one of these options in the Model tab of the Changing Model Units dialog box:
• Convert dimensions—Change the parameter units and scale the values.
• Interpret dimensions—Change the parameter units without scaling the values.
Select the check box to convert the absolute accuracy value when changing model units.
