lifesaver! a lot of websites, being US-centric, uses imperial units a lot so this helps out a lot as a non-American

Does not recognize negative X degrees Fahrenheit properly on allthatsinteresting.com/yakutsk and produces a few NaN values on the WIkipedia article about Fahrenheit but otherwise very handy!

Very useful. People complaining about the add-on should check and adjust the settings. Most of their complaints can easily be solved.
