Yep, even here in the US, official research is usually done with the metric system as it is kind of a universal systems of measurements. I don't know why they just can't be "bilingual" about it and list both feet and meters on the sign especially considering many of the people who go there are not American. Then again that would mean having to have the words on the sign in a dozen or so different languages. Then again maybe the people there were just too cold to care what the sign says.
