How to Convert Bits to Bytes
To convert bits to bytes, divide by 8 then adjust for scale. Since 1 byte = 8 bits, this conversion translates bit-based measurements to the byte-based units used for storage capacity. Related: B to b conversion rate.
b measures data in bits—commonly used for memory addressing and low-level data specifications. You might also need: calculate b to PiB.
B measures data in bytes—the standard unit for file sizes, storage capacity, and what you see in file explorers. You might also need: how many Bytes in a Kb.
1 b = 0.125 B (using SI decimal standard) — or equivalently, 1 B = 8b.
b to B Conversion Formula
// Convert b to B
B = b × 0.125
// Reverse: Convert B to b
b = B × 8
b to B Conversion Examples
100 b = 12.5 B
256 b = 32 B
500 b = 62.5 B
1,000 b = 125 B
2,048 b = 256 B
What Is a Bit?
The smallest unit of digital information, representing a single binary value of 0 or 1. See also: how many PiB in Exbibits.
The bit is a fundamental unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. You might also need: Zettabytes Per Second to GiB/s.
Common uses: Network speeds, data encoding, processor architecture (32-bit, 64-bit) Related: convert b to Gibibytes.
1 b = 1 bits .
The bit can be abbreviated as b; for example, 1 bit can be written as 1 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 Mebibytes to B calculator.

💡 Storage Engineer Tip
Remember: 8 bits = 1 byte. When your ISP advertises "100 Mbps," divide by 8 to get your actual download speed in MB/s (approximately 12.5 MB/s theoretical maximum).

When to Convert b to B
Common scenario: Converting your internet speed (Mbps) to actual download rate in MB/s, or calculating real-world transfer capabilities. You might also need: convert Bits to Zebibytes.
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. Check out our GiB → B.
