Data Storage Converter: Bytes to Petabytes
Convert between all common data storage units — bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes — in either binary (1024) or decimal (1000) mode.
Formula
The calculator converts any input amount to bytes first, then distributes the result across all units. Choose Binary (1024) for computer memory/file systems or Decimal (1000) for manufacturer/marketing specifications.
Worked example
500 GB in binary: 500 × 1024³ bytes = 536,870,912,000 bytes = 524,288 MB. In decimal: 500 × 1000³ = 500,000,000,000 bytes = 500,000 MB.
Practical guidance
Binary vs decimal: the root of confusion
Operating systems report storage in binary (1 GB = 1,024 MB), but drive manufacturers use decimal (1 GB = 1,000 MB). This is why a "1 TB" drive shows about 931 GB in your file manager. Use binary mode for OS-compatible numbers, decimal for marketing specs.
File size and transfer speed units
When checking download times, convert file size to megabits (Mb) or megabytes (MB). Note the capital B: MB = megabytes, Mb = megabits. 1 MB = 8 Mb. Internet speeds are in Mbps (megabits per second).
Frequently asked questions
