I've been all over the world. Don't make assumptions based on your own argument.

  Well you sort of betrayed yourself imagining all those hapless foreigners, struggling to fill their cars in multiples of 3.8L .. In most countries you could go your whole life without having to know what a "gallon" is or even hearing the word.

  And have you seen anywhere people using 3.8l or 0.334 meters or 12.5cm as common measurements? Or in general, people having problems with expressing quantities in simple multiples or fractions of liters, (kilo)grams, and meters? I do understand that it is hard to adjust intuitions from one system to the other, but I can't imagine how someone can think that people have problems using the measurement system they learned in primary school.
