And frankly, the bar is not SI; its actually considered deprecated by those scientists.
In this case, it absolutely makes it so. The metric system which developed during the 18th and 19th centuries was not uniform. Not only was the length of a meter not standardized and there were errors in determine its length but there were a variety of units all considered "metric" used to describe the same thing.
This was solved by selecting six base units from which all measurements could be standardized and similarly, it was agreed what defined those base units. A seventh, the mole, was the last added in 1971.
All scientists in all nations use SI units for publication and communication. That makes it, by definition, very international.
Furthermore, if you read the thread, I was not addressing bars or Pascals as a measurement. I was answering the question as to what SI units are.
That’s a very internationalist viewpoint.
And you are still wrong as to the bar being part of the so-called “SI”. It is not.
