Explaining the metric system.
"Can you count to ten?"
"Yes...?"
" There you go!"

Metric: Consistently consistent
Imperial: Consistently inconsistent

US guy: 'i wont ever use metric'
UK guy: ...do you own a gun?
US guy:  'sure.. a glock 9mm'

I am metric to the bones. ages ago, an old British lady asked me how many stones I weigh. without missing a beat, I replied, "depends on the size of the stones". the look on her face was priceless.

"I dont do math"... The American answer to any question they can't answer.

Rest of the world: km/h
USA: glazed donuts/bald eagle

It is ridiculous that in the 21st century it is necessary to explain that measuring the distance of a deceased person's feet is stupid.

My favourite quote regarding measurement systems comes from the author Josh Bazell in his book Wild Things (never read it, I just really like the quote): “In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade—which is 1 percent of the difference between its freezing point and its boiling point. An amount of hydrogen weighing the same amount has exactly one mole of atoms in it. Whereas in the American system, the answer to ‘How much energy does it take to boil a room-temperature gallon of water?’ is ‘Go fuck yourself,’ because you can’t directly relate any of those quantities.”

Heidi looked more and more depressed when the narrator talked about the SI units. Don't worry, Heidi, you'll get your antidepressants. Dosed in milligrams.

The video could have mentioned a bunch of other benefits. For example: whenever I cook and I need to add 300 milliliters of milk, I can use scales to weigh 300 grams, because I know that 1 liter of water weighs 1 kilogram, and milk is close enough to water when it comes to weight. Also, paper sizes are based on the A0 size, which is exactly a square meter. Divide it into 2, and it is A1. Each halving gives A2, A3, and of course the most common size A4. This means 16 sheets of A4 is 1 square meter. The weight of the paper is often in grams per square meter; for example, 80gr/m2 means each A4 sheet weighs 5 grams. When I send a letter and I need to know how much it weighs to determine what stamp to use, I can simply count the number of sheets. I try to say: everything is connected, and it takes very little math to convert one measurement into another.

“In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade—which is 1 percent of the difference between its freezing point and its boiling point. An amount of hydrogen weighing the same amount has exactly one mole of atoms in it. Whereas in the American system, the answer to ‘How much energy does it take to boil a room-temperature gallon of water?’ is ‘Go f* yourself,’ because you can’t directly relate any of those quantities.”

the metric is based on the constants in our universe. the imperial is a bunch of lads getting drunk spouting random numbers.

Metric is science.
Imperial is the dark side of the force.

The more I watch your videos, the more I get the impression that people in the US live in a bubble, which made them lose contact to the reality of the rest of the world. This makes them appear to be arrogant, sometimes maybe even uneducated or stupid.

0:10 yes it is.

The most important thing is not even mentioned. Interchangability of units: 1kg of water being equal to 1 liter being equal to the volume of 1 dm³. 1 calorie is the amount of energy you need to increase the temparature of 1 gram (or ml) of water by 1°C.... Oh and metric paper (A-standard) is also amazing and superior over the US Letter paper because it keeps its aspect ratio (lenght/width) as you fold it in half. And the base unit A0 paper has exactly the size of 1m², fold it in half you have A1. Makes any design or printing work very effective

One of my favorite simplifications of the metric system is that a liter of water has a mass of 1kg. Need half a liter of water and only have a scale? Weigh out half a kg of water. This is genuinely useful around the kitchen.

Yes, the metric system is not just better, it is far superior

Short answer: YES
Long answer: Y                E                 S

Yeah, the metric system isn't only a great advantage for scientists and engineers, but also for school children. Attending school in Australia in the 60ies, I was pestered by having to learn all these unlogical imperial weights and measures tables off by heart. They're so silly and backward - back to the middle ages. Later, back in Germany, it was ever so easy to adjust to the metric system. No more learning off by heart.
