By that logic 2000 is the last year of the second millennium, 2001 is the first year of the third millennium, 2002 the second, and 2003 the third.

The era started at year 1, and not year 0. So the new millenniums starts at years that ends with 1.

It’s also the third millennium of the era. 1-1000 AD was the first, 1001-2000 AD was the second, and we are now in the third.

As you pointed out previously, nobody uses decimeters, so x10 errors are not that common.

I find it weird that when measuring height in metric, people using cm exclusively, i’ve noticed this a lot actually, people will use cm or mm in places where it arguably doesn’t make any sense. I could see the justification for doing math maybe, but like, that defeats the whole point of it being metric no?

Why is that defeating the whole point of being metric? If you know someone is 183 cm tall, you also know that they are 1.83 m tall. If its easier to say the length in cm, you do. No need for “one meter and eighty-three centimeters” or “one point eighty-three meters”, just “a hundred and eighty-three centimeters”. Often you just skip saying the “centimeters” part as well, because most people can see that you’re not the size of a skyscraper without getting a ruler out.

If he doesn’t end up as VP, he would be a good candidate for Mitch McConnell’s senate seat when he retires in 2026.
