Yeah, the metric thing is way easier. It's fine if some country still uses their old measuring system for internal affairs but the people should be schooled in what the rest of the world uses or they'll be the oddballs when they travel. Americans can no longer rely on being dominant anymore to just strut into any country and have everyone conform to them. They're going to have to learn other ways and other languages. At least enough to get by for the length of their travel.

In Canada we call it fuel efficiency. People still say mileage and then use how many kms they get per litre.
There was an attempt to describe how little you use it for a fixed amount of fuel. As in: this car uses only 5 litres per 100 kms whereas this other car uses 10 litres per 100 kms. It didn't catch on. Car culture doesn't care how little it uses, it cares about how much they can get out of something so people say it gets 30 k per litre.

Most asian languages don't have a separate he and she and you can hear it when they make mistakes speaking English. "That man there, she is... oh he is... tee hee."
Mandarin Chinese says "ta" for "that person". I agree that "they" isn't quite suitable since it's a plural thing but it is pretty common though.
Xe pronounced zee (or is it zeh?) is a bit awkward to my ears at this point. I wonder what Ze Frank thinks of this.
