About File Size Units

File sizes are typically measured in the following units:

  • Byte (B): The basic unit of digital information storage.
  • Kilobyte (KB): 1,024 bytes.
  • Megabyte (MB): 1,024 kilobytes or 1,048,576 bytes.
  • Gigabyte (GB): 1,024 megabytes.
  • Terabyte (TB): 1,024 gigabytes.
  • Petabyte (PB): 1,024 terabytes.

Note: While some contexts use decimal-based definitions (where 1 KB = 1,000 bytes), this converter uses the binary-based definition (where 1 KB = 1,024 bytes) which is more commonly used in computing.
