I know, but in America its weird to use the metric system on a regular basis, most people switch between the two but they don't really understand how it works besides centimeters and meters. I once was talking about the obscene length of something and I used kilometers instead of miles and I got the weirdest look from the people I was talking to.

That's not that awkward, just compare it to a truly awkward moment, and it's easy to brush off.
