Is 1KB = 1.024 bytes OR 1.000 bytes?

Everyone keeps saying that

1'000 KB = 1 MB (decimal) -> Megabyte (MB) 10^6 Byte = 1 000 000 Byte

1'024 KB = 1 MiB (binary) -> Mebibyte (MiB) 2^20 Byte = 1 048 576 Byte

But when you look at windows properties of a folder, you get:

Which clearly uses 1KB = 1024bytes (and it's not this "MiB" but still uses 1024). So, what's the veredict?

Yes, in causal discourse, it is either one - context sensitive.

  • Memory size tends to use 1024.

  • File size tends to use 1000.

Exceptions are common.

Else see Kilobyte.

Pedantic concerns like this include using K, when k should be used as in 1kB.
