A system of measurement, used by most of the world, based off of units that make logical sense, unlike the arbitrary US system people have grown accustomed to.
1 kilometer is 1000 meters, 1 meter is 100 centimeters, 1 centimeter is 10 millimiters.
1 mile is 1760 yards, 1 yard is 3 feet, 1 foot is 12 inches.

The United States government's hopes of switching to the metric system were dashed once they realized it would cost billions of dollars.

Me: Yeah we went 135 miles per hour for about 5 minutes, the cop was gone.

European cousin: Cool?

A measurement systembased off the number 10, the size of the earth, and proprties of water. It was intruduced by French revolutionaries with the intention of creating system that was logical and easy to use, and because the previous system had been based on the feet of the king, whom they had killed.

In practical terms, one metre is a pace, half a litre is a large drink, which ways about half a kilogram, and all temperatures below -20 celsius and above 35 celsius are unbearable.

Theoretically all major nations except the united states use the metric system. In practice, all nations including the united states use a mixture of the metric system and older units.
Scientists generally use the metric system almost exclusively, but the average man on the street still finds it a bit abstract.

The Metric System is the punishment technique used in every country in the world except the United States for disobedient children in primary school. When a student behaves poorly, an instructor may use a meter stick to reprimand said student. In fact, the weapon wielded by instructors, the meter stick, is regulated by the IMSA (International Metric System Association).
Example of Metric System in use:

Instructor: You failed your test, Thomas
Thomas: You failed to educate me.
Instructor: THE FUCK YOU SAY TO ME TOMMY!?! *pulls meter stick out of pocket and beats child
