Data Storage Converter

Convert bytes using SI decimal prefixes and IEC binary prefixes as separate systems.

Exact defined conversion

1.048576 MB

1 MiB → Megabyte (1000² B)

Cross-system conversion: IEC binary → SI / metric. Factors are not silently aliased.

Systems: iec-binary → si.

Assumptions

  • SI prefixes kB, MB, GB, and TB use 1000ⁿ bytes.
  • IEC prefixes KiB, MiB, GiB, and TiB use 1024ⁿ bytes.
  • 1 byte = 8 bits. Ambiguous “KB = 1024” is not offered.

Examples

  • 1 kibibyte = 1024 bytes.
  • 1 kilobyte = 1000 bytes.
  • 1 mebibyte = 1.048576 megabytes.

How to use

  • Enter a non-negative quantity.
  • Choose a SI decimal unit or an IEC binary unit. The groups are separate on purpose.
  • Swap to compare the same quantity in the other system.

Limitations

  • Disk-maker “GB” marketing and operating-system “GiB” labels often disagree. This tool shows the definitions, not a vendor’s label.
  • This is not a file-conversion or encoding tool.

FAQ

Why is there no KB option?
KB is historically ambiguous. Use kB for 1000 bytes or KiB for 1024 bytes.
Does DevToolMage own this?
No. Byte prefixes are measurement. Encoding, hashing, and timestamps stay on developer tools.
