About data storage units

  • This converter uses decimal units, like drive makers and macOS: 1 KB is 1,000 bytes, 1 MB is 1,000 KB, and so on.
  • Windows reports sizes in binary units, where 1 KB is 1,024 bytes. That's why a 1 TB drive shows up as about 931 GB in Windows.
  • A byte is 8 bits. Internet speeds are measured in bits per second, so a 100 Mbps connection moves about 12.5 MB per second.
