The web’s a pretty international place, so don’t be surprised if you run into a unit of measurement you don’t understand from time to time. With the Converter extension for Firefox, however, you’ll be ready to convert almost any unit in two clicks.

Using this extension couldn’t be easier: just highlight the measurement you don’t understand, right-click and you’ll see your conversion. Heck, this thing can even convert one currency to another.

If Converter comes across something it doesn’t understand it will give you the option of manually selecting what unit you’re trying  to convert to what. You can get a good understanding of the sorts of units Converter can handle by checking out their examples page.

You can even embed this service into your website, allowing everyone who visits to make use of it regardless of the browser they use. This can be a useful tool for your readers, so check it out.
