The ship bringing the official kilogram and meter from Europe to the United States sank in 1790 something.
And they apparently didn't order another one.

The crowd impact the game. Both for the players on the field and the referees making important calls.

Fans. Noise level can have a huge influence. If you can’t hear communication/teamwork becomes a lot more difficult.

Reply to comment by Frednotbob in ELI5: Why do imaginary numbers even need to exist? by Tharsis101
For basics i is basically the square root of negative 1, this lets it do a couple useful things cause when dealing with control systems you can help avoid real zeros by tweaking the controls to create zeros at imaginary points ( which for a quadratic is always in a A +- root(B) form). So instead of stalling out it will occilate. For a simplified case, imaginary numbers let us make a cruise control that won’t just stop working on a highway.

Reply to ELI5: How does a beer bottle top stop the gas in the bottle from escaping enough for it to remain fizzy for extremely long times? by trumps_baggy_gloves
Worth noting that non-twist beer bottle tops are called Crown seals and are the most effective seal for a bottle.

That's a bit missing his point of there not even existing imperial equivalents to volts and amps, and why that is.

Although we've known a long time about electricity and magnetism, a broad based theory about them is a fairly recent discovery. (maybe 1800s). This was preceded by the metric system which was introduced in 1795 - so a lot of standards were already "established" before measures like volts and amps were defined.
Things like weights and distances, though, are very common measures and every civilization needed them even from ancient times thereby resulting in many different measures. By the time things like voltage and amperes came into broad use (outside of scientific circles), the SI system was already firmly established and there was no reason for alternative measures.
Note that the watt is a standard unit of power in the SI system. However we still use things like horsepower (1 HP = 746 W) and BTU/hr as non-SI unit measures of power. One used even today for engine power output and the other for cooling and/or heating systems. So not quite "standardized".

We did this in college. I don't know how much of it is placebo, but we did it for a year or so and thought it worked.
Heads up to anyone contemplating this - it makes your filter taste like booze. If you're going to do this, set one filter aside just for vodka and don't use it for water.

You can owe the mob 5 sheep. Which means that if you want to have 2 sheep, you'd better buy 2 sheep so you can pay your debts before you start farming wool.
And you can have 1 2/3 pizzas, because you bought two and then ate a third of one.
Sure, you can't have -pi hamsters, but if you have a circular sheep pwn, then you'll need to have pi times twice the radius of fencing, otherwise your sheep will escape.

Just like we standardized on kms, nms, etc. Only few countries in the world are using miles, and only conventionally - even US scientists rely on metric system.
The whole metric system is based on constants like kilogram, meter, second, etc. That conveniently correlate with each other and are used almost universally - first they were defined by well-preserved objects (e.g. 1kg steel block), now we define them using physics.

Measurements relevant to electricity are a fairly new phenomenon and the pioneers who worked on it mostly impacted the entire world. Similar to how the "decibel" coined by Bell Laboratories is named after Alexander Graham Bell, and at that point the international community was on board with keeping up with the latest research relevant to modern technology.
Humans have been doing things like walking to market and baking bread and weighing witches to see if they'll float for a very long time. There was no international community to manage those measurements.
Then the French and the Europeans and the communists came along with the metric system and Americans said screw you all.

Drinking vodka straight, I feel I can 100% tell the difference. For me its that smooth, no taste & no burn feel. I dont make "that face" after doing a shot of good vodka.
Mixed drink you can basically throw in anything and it gets covered up...for the most part.

A lot of the comments answer why we have them but an interesting thing is the way they came up with them (from what I remember). Basically, math always evolves, and mathematicians were at a crossroads trying to figure out problems. They needed a number that when it was squared resulted in a negative number. Previously thought impossible because squares can only be positive numbers. What’s the answer? Create a new “imaginary number” that solves your problem, and it leads to many different applications and uses in modern mathematics. Always a complicated topic to think about though!

This is also why you have to be careful with moonshine. If you don't know what you're doing you could get too much methanol in there and cause serious issues.

An ex of mine chugged everclear from the bottle because he thought it was vodka, and I don't think I've ever seen anyone that fucked up.

It stems from being in your home city. Not having to travel. Playing in the stadium you’re used to. Sleeping in your own bed that week. Fans will be much louder and on your side as well.
