Where units of measurement are required e.g. in the width attribute of colspec or the height and width attributes of file, the following abbreviations should be used.
| Unit | Example | Explanation |
|---|---|---|
| pt | width="12pt" | points |
| pi | width="12pi" | picas ("pc" preferred) |
| pc | width="12pc" | picas |
| cm | width="12cm" | centimeters |
| mm | width="12mm" | millimeters |
| in | width="12in" | inches |
Note: There should be no space between the numerals and the units i.e. "12 pt" is incorrect.
