Welcome to the Q&A Forum

It probably won't hurt your rankings, but we would need a URL to say more. Do you see links to the fonts in your source code? If it's not immediately obvious you could try running a crawl to see where these are being linked from. It's probably a simple matter of cleaning up some CSS.

I think Tom lays this out quite well and I would follow this advice.

Okay, great.  Thanks for your responses.  It sounds like I should be okay using the same content and since I will be changing to metric units and will be using localized terms and different folders/paths.

I will recommend that you take a look at the Moz Guide on this topic: http://moz.com/learn/seo/international-seo Google will differentiate content if it is served on a different domain in a different content. So a 1:1 relationship should in theory not create DC as long as it is not in the same language. However, I would take the time to make sure that the content is written properly in the right tongue and take into account local cultural aspects. Which method are you using? domain.com/fr/ fr.domain.com or domain.fr?
