1 B equals 8 bit. To convert B to bit, multiply the value by 8; divide by 8 to convert back. Enter any number above and the result appears instantly — free and entirely in your browser.
How do you convert B to bit?
The conversion formula is bit = B × 8. The conversion factor is fixed by definition, so the result is always exact.

What is B (B)?
A byte is eight bits and the basic unit of file size. One character of text is roughly one byte; larger files are measured in kilobytes, megabytes and gigabytes.
What is bit (bit)?
A bit is the smallest unit of digital information, a single 0 or 1. Eight bits make one byte. Network speeds and data rates are usually given in bits.
Why convert B to bit?
Decimal units (KB, MB, GB) are used by drive makers and networks; binary units (KiB, MiB, GiB) by operating systems and RAM. The roughly 7% gap per step is why drives look 'smaller' than advertised.
Storage makers use decimal units: 1 GB = 1,000 MB = 1,000,000,000 bytes. Operating systems often show binary units, where 1 GiB = 1,024 MiB — which is why a '1 TB' drive appears as about 931 GiB (IEC 80000-13).
