It's a rather bizarre mix of units here - the transportation systems interchangeably uses kilometers and miles, some shop owners by principle refuse to use kilograms and insist on "pounds" (without realising a "pound" is defined in law using grams and that there was like a dozen of "pounds"), fuel efficiency is measures in miles per gallon, but it's a different gallon from the one used in the US. In general, the whole units situation is nothing but a confusing dick contest.,,
