Data Storage Converter
Convert bytes, kilobytes, megabytes, gigabytes, terabytes and more.
SI vs. Binary Prefixes
There are two conventions: SI (decimal) — 1 KB = 1,000 bytes — used by hard-drive manufacturers and network speeds. Binary (IEC) — 1 KiB = 1,024 bytes — used by operating systems. This discrepancy is why a "1 TB" hard drive shows as ~931 GiB in Windows. This converter supports both systems.
Common Conversions
- 1 byte = 8 bits
- 1 KB = 1,000 bytes (SI) / 1,024 bytes (binary)
- 1 MB = 1,000 KB = 1,000,000 bytes
- 1 GB = 1,000 MB = 10⁹ bytes
- 1 TB = 1,000 GB = 10¹² bytes
- 1 GiB = 1,024 MiB = 1,073,741,824 bytes
