How it works

How to convert bytes to bits

  1. Know the formula

    bit = B × 8. In words: multiply the number of bytes by 8.

  2. Work an example

    10 B → 80 bit. Round to two or three decimal places for everyday use.

  3. Or type it in

    Enter any value in the converter above and the answer appears instantly, in both directions.

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.
