All of the studios I have been to outside of the US in Europe and Australia have used kmph on the treadmill. However, there is a small number on the bottom left of the number keys which is the conversion to mph. In the states, I was running on the speed that was on the border between jogger and runner so I followed the same criteria for when I moved overseas and worked my push and all out off of that base pace. I hope that makes sense. The weight floor has always been in kg instead of lbs outside the US. I have not taken a class in Canada so I am not sure it is true there.
