Bits to Bytes (bit to B) Converter
1 bit (bit) = 0.125 bytes (B). To convert bits to bytes, multiply by 0.125: 25 bit × 0.125 = 3.125 B.
Quick facts
- 1 bit = 0.125 B
- 1 B = 8 bit
- Formula: B = bit × 0.125
- Quick estimate: multiply by about 0.13
How to convert bits to bytes
- Take the value in bits.
- Multiply it by 0.125 (the number of bytes in one bit).
- Round the result to the precision you need.
Worked example: 25 bit × 0.125 = 3.125 B.
To convert bytes back to bits, multiply by 8, or divide by 0.125.

What is a bit?
The smallest unit of digital information, a single binary 0 or 1. Used for internet connection and data transfer speeds.
What is a byte?
Equal to 8 bits, commonly representing a single character. The base unit for measuring file and storage sizes.
Frequently asked questions
How many bytes are in a bit?
There are 0.125 bytes in 1 bit (1 bit = 0.125 B).
How many bits are in a byte?
There are 8 bits in 1 byte (1 B = 8 bit).
How do I convert bits to bytes?
Multiply the number of bits by 0.125. For example, 10 bit × 0.125 = 1.25 B. To convert back, multiply by 8.
What is 10 bit in bytes?
10 bit = 1.25 B.
What is 100 bit in bytes?
100 bit = 12.5 B.
Is the conversion exact?
Yes. The factor comes from the official definitions of both units (IEC 80000-13 for binary (1,024-based) and decimal (1,000-based) prefixes; this site uses the binary convention shown in each definition). Results are shown to up to 10 decimal places; round them to suit your purpose.
