Convert bytes to bits
Bytes to bits. Enter a value to convert, or use the bytes to bits chart further down the page.
1 byte equals 8 bits. Going the other way, 1 bit = 0.125 bytes.
Note. This converter uses the binary convention: 1 KB = 1024 bytes, 1 MB = 1024 KB, 1 GB = 1024 MB. That is what Windows, macOS and Linux report. Storage manufacturers instead use decimal SI units where 1 GB = 1,000,000,000 bytes, which is why a “1 TB” drive shows up as about 931 GB.
How to convert bytes to bits
To convert bytes to bits, multiply the byte value by 8. You can also divide by 0.125 to get the same answer.
b = B × 8
Worked example
Convert 8 B to bits:
8 B = 64 b
