Coca-Cola Co. can’t do math

I decided to have a Coke today and in order to scare myself into not drinking them anymore, I looked at the nutrition facts label.

Nutrition Facts Standard Serving This Package
Serving Size 8 fl oz 20 fl oz
Servings per container 2.5 1
Calories 100 240

Is this just another example of how Americans are falling behind in math? Or do calories not scale linearly with volume?

Actually, there is an explanation — apparently 8 fl oz = 240 ml, but 20 fl oz = 591 ml! So really the problem is that the metric system of measurement is nonlinear. That’s because it was invented by Europeans, who are trying to cheat us, clearly. That, or Americans are falling behind in math.
