Bit to Byte Converter
One Bit equals 0.125 Byte (1 bit = 0.125 B). Multiply a Bit value by 0.125 to get the equivalent in Byte. Use the calculator above for instant results, or follow the formula, worked 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 Bit × 0.125 = 1.25 Byte.
- 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 Byte (1 bit = 0.125 B). Bit to Byte conversion comes up most often in network bandwidth ratings and in encryption key lengths, typically when figures need restating for file size fundamentals.
Precision and Rounding: This converter uses the binary convention (1 KB = 1,024 bytes), which matches how operating systems report file and memory sizes. Storage manufacturers label drives with decimal units (1 GB = 1,000,000,000 bytes), which is why a '1 TB' drive shows roughly 931 GB in your OS — check which convention your source uses.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
