Control the Display of Alternate Units
You can create dimensions in two systems of measurement simultaneously.
A common use of this feature is to add feet and inches dimensions to drawings
created using metric units. The alternate units appear in square brackets ([ ])
in the dimension text. Alternate units cannot be applied to angular dimensions.
If alternate-units dimensioning is on when you edit a linear dimension, the
measurement is multiplied by an alternate scale value that you specify. This
value represents the number of alternate units per current unit of measurement.
The default value for imperial units is 25.4, which is the number of millimeters
per inch. The default value for metric units is about 0.0394, which is the
number of inches per millimeter. The number of decimal places is specified
by the precision value for alternate units.
For example, for imperial units, if the alternate scale setting is the default
value, 25.4, and the alternate precision is 0.00, the dimension might look like
the following figure.
