Works for most metric conversions. Would like metric to imperial as well.

Fairly consistently picks up and converts units, though can miss due to formatting.

Would be nice to be able to see the original as well, or at least distinguish when a conversion occurred.

It's pretty useful for the units it provides. It would be incredible if more units / currency were supported, and that there was a way to tell if the unit was converted or not (a different color, maybe).

Thank you for the effort - looks promising. I hope we will eventually see more units supported.

If you are looking for inspiration: years ago another really nice guy (*) developed an extension named Converter, that worked really fine. In 2015 he ended development and released the code as Open Source - you can find it here https://github.com/Gutza/Converter

(*) in 2011 the extension stopped working after an update; for the first time I emailed the developer of an extension I used. The next day the issue was already fixed, and we exchanged some really nice emails - he was a great guy!
