Great app, this has been very useful. Thanks.
One minor annoyance Ive encountered is people using the em dash (—) instead of a normal minus (-). Not the apps fault in anyway but would be cool if it could account for this.

Great little tool; as an amateur chef in UK I use all the time to convert from Old American (F) to normal modern UK (C)

Useful but there needs to be a way to customize how the converted temperature is displayed. On some sites it overlays adjacent text and is difficult to read.

Very useful for european looking for informations on US websites. It will be great to have similar addon for other units (weight, volume).
Also it will be nice if it could convert automatically all temperatures in selected text, or whole website.

I've always hated websites that don't offer the option to change temperatures to celsius, but now I don't have to hate these websites anymore because now I can convert them with this addon. Much more faster than opening a new tab and opening a converting website!
