Expert writing Tips

Best practice

When describing dimensions in technical documents, always include the unit of measurement (mm) to avoid ambiguity. Be consistent with the use of "mm across" throughout the document for clarity.

Common error

Avoid mixing units of measurement within the same context. If you start with millimeters, maintain that unit. Switching to inches or centimeters mid-description can cause confusion and errors.
