Actually, here in the Netherlands, that's not uncommon to ask.
Fluitje (whistle): 25 cl
Amsterdammertje (little Amsterdammer): 33 cl
Except that here in Amsterdam that one is called a Vaasje (little vase.) Tried to get one of those in Utrecht and it didn't work.
In my native Finland a moderate 8-pinter night, of course meant that you had 4L of beer and probably are in need of about 400mg of Ibuprophen in the morning with your coffee.
In Russia you order Vodka by grams.... and lemme have 200 grams of Russky Standart with my dinner, please :)
And yes, The Size is in centimeters but that's only for me and my SO to know.
On a more serious note one should not forget that in aviation there are constant problems stemming from former eastern-bloc countries and their aircraft avionics systems using metric and the pilots having to convert from miles/feet when flying abroad. In such potentially dangerous situations not being able to visualize the distances/altitudes intuitively when making decisions can lead to excessive fatalities.
I wonder how many fatalities it would cost for the aviation industry to suddenly migrate to SI units and whether it would be considered worth it?
