There are over seven billion people that think otherwise.

Seven billion people that have trouble dividing things into thirds. 1/3 of a foot is four inches. 1/3 of a half-meter is some number with infinitely repeating decimals. Inches and feet are practical for measuring most hand-held items. Metric's only option is centimeters, but a single centimeter is too small for many of those measurements. The only reason a liter is practical is because people can picture a liter of cola. Everyone knows how much a gallon is. Pints are ubiquitous, obviously. What kind of sissy orders a half-liter of Shiner? (To be fair, I have no idea how metric users can possibly order their beer.)

"I have no idea how metric users can possibly order their beer."

By the mug. The very precise Germans require that every mug or glass has a line printed on it with the volume in in ml (milliliters) printed at the line. The beer must fill to the line, not including the head.

A liter is just a bit more than a quart, or just a bit more than two pints. You'll get drunk just a bit faster on German 500 ml mugs compared with English pints. A US wine bottle is actually 750 ml, just under a quart.

“1/3 of a half-meter is...” 6-9/16 inches. For all practical intents and purposes.
