The option to change units of measurement for a document is under the Rulers selection of the Format menu. If you have selected Centimeters as the units of measurement for a document, AppleWorks will convert measurements entered in Inches, Picas, etc. into their Centimeter equivalents. This type of conversion takes place in areas including Format Document, Column Height in Spreadsheets, and Object Size in Drawing documents.
However, the Create Labels Assistant does not convert values. If a value of '1.0 cm' is entered, it will be interpreted as '1.0 in'. The same is true if the document's rulers are set to Millimeters, Picas, or Points.
This behavior can be seen in the Windows and Macintosh versions of ClarisWorks/AppleWorks 5. A workaround is to use the Calculator under the Apple Menu to convert from your intended custom size to Inches, using the chart below:
| Intended unit of measure | Divide by |
| Centimeters | 2.54 |
| Millimeters | 25.4 |
| Picas | 6 |
| Points | 72 |
