Convert between all digital storage units instantly with our free Data Storage Converter. Bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes — supports both decimal (SI) and binary (IEC) standards. No account required.
Data storage units are relevant in more situations than ever — comparing hard drives, understanding cloud storage plans, working out file sizes for uploads, or simply making sense of the numbers on your device's storage menu. The difference between GB and GiB (gibibytes) often causes confusion — our tool supports both.
Decimal (SI) vs Binary (IEC) Units
- Decimal (SI): 1 KB = 1,000 bytes, 1 MB = 1,000,000 bytes (used by storage manufacturers)
- Binary (IEC): 1 KiB = 1,024 bytes, 1 MiB = 1,048,576 bytes (used by operating systems)
- This is why a "500 GB" hard drive shows as less in Windows — the OS uses binary units
Supported Storage Units
- Bits, Bytes, Kilobytes (KB/KiB), Megabytes (MB/MiB), Gigabytes (GB/GiB), Terabytes (TB/TiB), Petabytes (PB/PiB), Exabytes (EB)

❓ Frequently Asked Questions
Manufacturers use decimal GB (1 GB = 1 billion bytes). Windows uses binary GiB (1 GiB = 1,073,741,824 bytes). A 1 TB drive shows as ~931 GiB in Windows.
Decimal: 1 GB = 1,000 MB. Binary: 1 GiB = 1,024 MiB. The standard varies by context — storage marketing uses decimal, operating systems use binary.
1 petabyte (PB) = 1,000 terabytes (decimal). To put it in perspective, 1 PB could store about 200,000 HD movies.
Decimal: 1 GB = 1,000,000,000 bytes. Binary: 1 GiB = 1,073,741,824 bytes.
