Bits to Bytes Converter
One Bit equals 0.125 Bytes (1 bit = 0.125 B). Multiply a Bit value by 0.125 to get the equivalent in Bytes. Use the calculator above for your value, or check the examples and reference table below.

How to Convert Manually
Use these steps to convert Bit values to Byte without the calculator.
- Write down the value in Bit (bit) that you want to convert.
- Multiply that value by 0.125.
- For example, 10 Bits × 0.125 = 1.25 Bytes.
- Label the result as Byte (B).

About Bit and Byte
The bit is the smallest unit of digital information, a single 0 or 1. Network speeds are quoted in bits per second, which is why a '100 Mb' connection downloads at about 12.5 MB per second. The byte is 8 bits, the basic addressable unit of computer storage. One byte holds a single ASCII character, and all file sizes build up from it. One Bit equals 0.125 Bytes (1 bit = 0.125 B). Bit is used in network bandwidth ratings and in encryption key lengths. Byte is used in file size fundamentals.
Precision and Rounding:This converter keeps SI decimal prefixes (1 KB = 1,000 bytes) separate from IEC binary prefixes (1 KiB = 1,024 bytes). Match the symbol used by your source before converting because some operating-system interfaces display binary quantities with decimal labels.
See our guide to megabits vs. megabytes if you're unsure which one your download speed is quoted in.
Data units follow NIST guidance: decimal SI prefixes use powers of 1,000, while IEC binary prefixes use powers of 1,024 (reference).
