Anyone who goes to an American grocery store today needs to understand the metric system. Milk and water is sold by the gallon, but soft drinks are sold either by the fluid ounce or liter, depending on the size of the bottle.or can.
Beer is generally sold by the fluid ounce, as many local jurisdictions have taxes on beer based on that measurement. Wine is almost exclusively metric, even if made here.
It's all quite stupid.
