About this Add-on
You don't have to choose the units from drop-downs -- Converter understands the units and converts them in place. Convert either a single measurement (select and right click), or the entire page (click the icon).
For bug reports and suggestions, please visit the feedback page. For more details, please visit the project's homepage.
Please read this before reporting bugs:
- If you want to add more extensive comments which require feedback (e.g. bugs, suggestions), please use Converter's feedback page instead of writing reviews;
- If you report bugs, please make sure you include the URLs of pages where you encountered the issue you're describing;
- If you want to suggest new formats, please mention them explicitly.
