Is there any measurement system according to which 1 kilobyte = 1024 bytes?

Question

IT terminology

I learned about gibibytes, started digging and found out that 1 kilobyte = 10 ^ 3 = 1000 bytes.
But 1024 bytes = 1 kibibyte.
At school, at university and in many articles, words associated with a byte (kilobyte, megabyte, etc.) are operated as 2 to a certain extent, although according to SI this is incorrect. Is everyone who writes like this just illiterate people, or is there some kind of unit/measurement system according to which 1 kilobyte = 1024 bytes, not 1000 bytes?

Answer 1

My answer has disappeared.
In the Russian Federation, there are 24 bytes more in a kilobyte than anywhere else. Decree of the Government of the Russian Federation of 2009.

Answer 2

There is no such system. It would be correct to say "kibibyte", "mebibyte", "gibibyte" and so on. But out of habit, everyone says "kilo-", "mega-", "giga-". Except manufacturers of hard drives and other drives. They use these terms correctly.
So yes, purely formally, those who mean 1024 bytes by a kilobyte are illiterate people.
