Data Size Converter
Convert data sizes between decimal (B, KB, MB, GB, TB, PB) and binary (KiB, MiB, GiB, TiB) units. Understand file sizes, storage requirements, and bandwidth calculations instantly.
Data Size Conversion
Decimal (SI): 1 KB = 1,000 bytes, 1 MB = 1,000 KB. Binary (IEC): 1 KiB = 1,024 bytes, 1 MiB = 1,024 KiB. Storage manufacturers use decimal units, while operating systems use binary — this discrepancy explains why a "500 GB" drive shows as ~465 GiB.
