Metre is an SI unit and spelt the french way, "meter" is something you find in poetry. You are also out of date in your definition. The metre is now defined as a fraction of the speed of light.

A multiple of the wavelength of a particular spectral line, I think.

The Kilogram has a new definition since 2019. One that is a little to complicated for me!

Anyway, this kind of thing leads to unending debate, so I think it is time to retire from the fray.

This is the kind of topic that Wikipedia does well.

I learned in school that a kilogram is 1,000 grams, and that a gram is the weight of one cubic centimeter of water. I don't know how a definition of something can be changed. That seems absurd to me. Then again, I think it seems absurd to change the name of a city or sports team, but that kind of thing seems to be going on all the time these days. Change is constant. Then again, some things never change, right?

Next we'll find that global warming advocates have decided to change the definition of zero degrees.
