This did have a check mark by it:
Use imperial units
Note that there is a specific setting at the Profile stats page for the exports of those.
I tried to figure out if there was something else I had to do on the Profile stats page since it was underlined and clickable, but It didn't help me any (I don't know my way around computers very well). I did click update settings even though I didn't change anything. I guess I will wait and see if anything happens.
