SI: 1 KB = 1,000 bytes. IEC: 1 KiB = 1,024 bytes.

Decimal vs Binary Units

Storage manufacturers use SI prefixes (1 KB = 1,000 bytes) while operating systems traditionally use binary units (1 KiB = 1,024 bytes). This discrepancy causes the apparent difference between advertised and usable storage. Our converter supports both standards simultaneously.
