How Pirates Of The Caribbean Hijacked America's Metric System (npr.org)
If the United States were more like the rest of the world, a McDonald's Quarter Pounder might be known as the McDonald's 113-Grammer, John Henry's 9-pound hammer would be 4.08 kilograms, and any 800-pound gorillas in the room would likely weigh 362 kilos. NPR explores: One reason this country never adopted the metric system might be pirates. Here's what happened: In 1793, the brand new United States of America needed a standard measuring system because the states were using a hodgepodge of systems. "For example, in New York, they were using Dutch systems, and in New England, they were using English systems," says Keith Martin, of the research library at the National Institute of Standards and Technology. This made interstate commerce difficult. The secretary of state at the time was Thomas Jefferson. Jefferson knew about a new French system and thought it was just what America needed. He wrote to his pals in France, and the French sent a scientist named Joseph Dombey off to Jefferson carrying a small copper cylinder with a little handle on top. It was about 3 inches tall and about the same wide. This object was intended to be a standard for weighing things, part of a weights and measure system being developed in France, now known as the metric system. The object's weight was 1 kilogram. Crossing the Atlantic, Dombey ran into a giant storm. "It blew his ship quite far south into the Caribbean Sea," says Martin. And you know who was lurking in Caribbean waters in the late 1700s? Pirates.
America is inching its way towards the metric system.
Uh, not all that much - in the UK, where the metric system is a required thing by law, the McDonalds Quarter Pounder is *still* called the Quarter Pounder, because thats its product name. Its pre-cooked weight may be given in metric, but that doesn't alter the product name. In France its the Royal for the same reason, thats its product name.
In the UK, you can still buy a 64Oz Club Hammer or a 16Oz Rubber Mallet, and a 800-pound gorilla is still a 800-pound gorilla - again, the requirement for metric doesn't change these things.
The speech from Pulp Fiction is cool and all, its just not so much based in reality.
If you really want to see the US move to the metric system, stop using soft metrics. People in the US think the metric system is complicated because they are always being told to convert from English to Metric measure, with the metric being non integral. No, a 9 lb hammer would not be 4.08 kilograms. it would be 4 kilograms. And a Quarter Pounder would be a 100 Grammer. If you want to think in metric, start with integer metric measures and don't worry about conversion.
I remember when Jimmy Carter was trying to move the US to metric in 1977, I saw a giant sign that said 1 inch equals 2.54 cm. Think Metric! At that moment I knew metric was dead in the US.

It would be a 100 gram patty, 5 kilo hammer, or half a ton gorilla. There is no need for precise conversion, and a good easy number is what marketing people and idiom pioneers would choose/use.

That is why we still celebrate talk like a pirate day! To commemorate the day we defeated the metric system!
I'll consider metrics when the clock, day, and calendar are also 'neatly' divided by 10.
The first iteration of metric, right after the French revolution, included a ten-hour day of hundred-minute hours, with hundred-second minutes. The months were renamed from the antique Romanesque hodgepodge to be more logique: March became Germinal, the month when things grew, October became Brumaire, the foggy month, and November became Nivôse, the snowy month.
But people wanted quarter-hours and all the other integer divisible units they were used to, and the month-renamers were reminded that, malheureusement, the new month names only made sense in Paris. In places like Martinique and Réunion, the new names made no sense.
There's a reason these are called "customary" units. They were contrived to be convenient for highly specialized and closely related tasks.
For example a rod was the typical length of a medieval ox-goad. If you laid out a line 40 rods long, you've got a furlong, which is about the length of furrow a man with a single ox could plow without giving his animal a rest. If you lay out a rectangle 1 furlong by four rods, you have an acre, which is about what he could plow in a day.
Customary units are far more convenient for the tasks they're optimized for. But it's the modern need to do more complex calculations relating things across problem domains that makes them awkward.
