What's amazing is how we mix the two. Case in point, my wife and I are both runners, she measures her pace in minutes per mile, I use minutes per km. When we exchange stats we have to do the conversion. She does it as her running club uses the mile convention. This is despite the fact that we're doing 10 km races. So you're running a 10 km and talking about a '7 minute mile'?! We're an eccentric bunch!
