right, I'm fairly metric-fluent. Advocate for the switch and whatnot. I just had not personally seen centiliter used on a commercial product like that. I'm guessing each country (or perhaps it's more language specific?) chooses different common units. In my experience, I have only seen milliliter and liter used for beverages, and gram and milligram used for foods. I know the others exist, and I'm sure someone somewhere measures distance or size in decimeters, it's just not something I've seen someone doing.
