Awesome stuff Miloo, this extension goes above and beyond, it's way more versatile than would have hoped.

I do quite like this, but I wish it had the ability to whitelist domains you don't want it to run. I have to turn it off because it's messing with code on GitHub and similar sites. Please consider adding such a feature.

Doesn't work on new reddit, does work on old reddit though.

EDIT: It works if you enable continuous conversion.

doesn't work well on reddit, when I click a post it doesn't show up at all, when I reload the page it shows up but then disappears after half a second.

I'm sourcing special containers from the US and they have all measurements in inches and cu/ft, while I need everything in cm and liters. This add-on is really a life saver.

Before it was really annoying because any number between quotes would be converted (i.e "34" is assumed to be 34" and conversion is made.

This behavior while still present, it has been properly styled to avoid confusion, I love it now really

Imperial units are 💩. Thanks for this extension.

Seems to work good. I imagine that it could create problems on some websites but I have not encountered any so far.

Please introduce an option like color highlighting the converted units!

Of course this would not be necessary if the USA would just give up their ridiculously outdated units and finally change to metric units!

This is a wonderful add-on. Finally I don't have to stand these ugly non SI units. It would be nice to also have the option to remove the Imperial altogether and provide a tool-tip if something was converted.
The basic add-on already deserves a 5/5, however. Thank you very much!

One thing which is funny is that the description says "Convenient for amazon shopping, cooking, etc." .... Tablespoons do not get converted yet, but then again which idiot would measure in spoons and then say it is an exact thing in the first place.... (ah yes, the internet)

This addon was exactly what I was looking for! I had gotten completely fed up with trying to parse outdoor gear specs back and forth between metric and imperial. This makes it effortless.

I hate imperial units so much! Thank you! You are my saviour!

I have been looking for something like this for a while (I sorely miss the old "Converter" extension!). I have just installed it and the first impression is very positive! Thank you!

[EDIT] first impression confirmed - works really fine for me.

If you are looking for ideas, to further develop this project - In 2015 the developer of the Converter extension ended development and released the code as Open Source - you can find it here https://github.com/Gutza/Converter
