About Digital Storage Conversions

Digital storage units cause widespread confusion due to the historical overlap between decimal (SI) and binary (IEC) prefixes. Storage manufacturers advertise in decimal units (1 GB = 1,000,000,000 bytes), while operating systems historically reported in binary units (1 GiB = 1,073,741,824 bytes) — a 7.4% discrepancy that grows with larger units. A '1 TB' drive shows approximately 931 GiB in your file manager. The IEC introduced unambiguous binary prefixes (kibi-, mebi-, gibi-) in 1999, but adoption remains inconsistent. Our converter clearly distinguishes between decimal and binary prefixes, helping IT professionals, developers, and consumers accurately compare storage specifications.
