As SI prefixes, they’re all multiples of ten, technically speaking. So referring to 1,024 bytes as a kilobyte is incorrect, it’s 1.024 kilobytes or 1 kibibyte. Microsoft deciding to ignore industry and international standards is the reason for the confusion.
But either way, hard drive manufacturers will sell a 1TB drive, and Windows will see that as a 935GB drive - that’s basically the difference between 2^40 bytes vs. 10^12 bytes
