Frequently Asked Questions

Can I convert other units using the CONVERT function?

Yes, the CONVERT function supports a wide variety of units including weight, distance, time, and temperature. You simply need to change the unit abbreviation arguments, for example, =CONVERT(A1,"m","yd") to convert meters to yards.

How do I prevent text cells from being affected during a bulk Paste Special conversion?

Before using Paste Special, highlight your range, press F5 to open 'Go To', click 'Special', and select 'Constants' with only the 'Numbers' checkbox ticked. This ensures your text markers remain completely unchanged during the divide operation.

Why is my CONVERT formula returning a #N/A error?

A #N/A error in the CONVERT function usually means that the unit abbreviations are misspelled or incompatible. Ensure you are using the exact, case-sensitive abbreviations recognized by the software, such as "mm" for millimeters and "ft" for feet.
