How to Convert Bytes to Bits
To convert bytes to bits, multiply by 8 then adjust for scale. This converts byte-based storage measurements to bit-based units. Related: b to B converter.
B is a byte-based unit used for measuring file sizes and storage capacity. Try the B to Gb calculator.
b is a bit-based unit—multiply bytes by 8 to get bits. You might also need: convert GB to b.
1 B = 8 b (using SI decimal standard) — which means there are 8bits in every byte.
B to b Conversion Formula
// Convert B to b
b = B × 8
// Reverse: Convert b to B
B = b × 0.125
B to b Conversion Examples
100 B = 800 b
256 B = 2,048 b
500 B = 4,000 b
1,000 B = 8,000 b
2,048 B = 16,384 b
What Is a Byte?
A byte consists of 8 bits and is the standard unit for measuring digital storage. One byte can represent 256 different values (0-255). Use our KB → TB.
The byte is a fundamental unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Use our Mebibits Per Second to Petabits Per Second.
Common uses: File sizes, memory addressing, character encoding (ASCII, UTF-8) Learn more: Bytes to Kilobytes converter.
1 B = 8 bits = 1 bytes.
The byte can be abbreviated as B; for example, 1 byte can be written as 1 B.
What Is a Bit?
The smallest unit of digital information, representing a single binary value of 0 or 1. You might also need: Nibbles to Bits calculator.
The bit is a fundamental unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. See also: convert Yobibytes to Exbibits.
Common uses: Network speeds, data encoding, processor architecture (32-bit, 64-bit) You might also need: Gigabytes Per Second to Kibibytes Per Second conversion.
1 b = 1 bits .
The bit can be abbreviated as b; for example, 1 bit can be written as 1 b.

💡 Storage Engineer Tip
Multiply bytes by 8 to get bits. A 10 MB file requires 80 Mb of bandwidth—essential when calculating transfer times over network links.

When to Convert B to b
Common scenario: Calculating bandwidth requirements for file transfers, or estimating how long uploads/downloads will take. Related: B to Yottabits converter.
Other situations include storage planning for calculating how much data fits in a given capacity, file management for understanding sizes across different scales, cost estimation for budgeting cloud storage, and backup planning for determining media requirements. Try the Pebibytes to b calculator.
