Do unit conversion conveniently at the current selected text

Select any text by mouse which includes a quantity (in Arabic numerals) with a unit, this "Unit Convert Selection" will automatically convert it to all supported units by displaying a bubble floating around the selected text. It's quick and easy. There is no need to select "from" and "to" in other conventional unit conversion tools. Unit conversion is done by "converts-unit" utility at https://github.com/ben-ng/convert-units

This is the best unit converter format I've seen: A simple selection gives you many different units with out even a click. Still there is room for improvement as other reviews have mentioned. Top one for me being the ability to set preferred units for each type of value. It might even be nice if the user could make their own units. I give 5 stars because there is still nothing even close to this out there.

I found the extension unsuited to my needs. I would like to see an option to select prefered units. It doesn't recognize feet and inches represented with prime and double prime marks (′ and ″) (single and double quote marks (' and ") work fine). Lacking an option to change color of text or background, conversions are usually unreadable when used with the Dark Reader extension. The extension exhibits erratic behavior when used in text boxes, sometimes not working at all, other times using CSS ... Show more

Select a dimension and a list of conversions pops up next to the original. Does exactly what I wanted. Would be great if you could turn off certain dims it converts too that you would never be interested in seeing to make the popup list cleaner but thats my only comment.
