Yeah, only the U.S.? I thought Canada uses Farenheit too.
Also we don't say "the house is two blocks away from here". It's confusing. We use kilometers than miles so we'd say "[#] of kilometers away" from here. And the speedometer of our cars uses KPH not MPH. But we drive on the right side of the road. Which is odd as most countries in Asia drive on the left side of the road.
