Bytes to Bits (B to bit) Converter
1 byte (B) = 8 bits (bit). To convert bytes to bits, multiply by 8: 25 B × 8 = 200 bit.
Quick facts
- 1 B = 8 bit
- 1 bit = 0.125 B
- Formula: bit = B × 8
- Quick estimate: multiply by about 8
How to convert bytes to bits
- Take the value in bytes.
- Multiply it by 8 (the number of bits in one byte).
- Round the result to the precision you need.
Worked example: 25 B × 8 = 200 bit.
To convert bits back to bytes, multiply by 0.125, or divide by 8.

What is a byte?
Equal to 8 bits, commonly representing a single character. The base unit for measuring file and storage sizes.
What is a bit?
The smallest unit of digital information, a single binary 0 or 1. Used for internet connection and data transfer speeds.
Frequently asked questions
How many bits are in a byte?
There are 8 bits in 1 byte (1 B = 8 bit).
How many bytes are in a bit?
There are 0.125 bytes in 1 bit (1 bit = 0.125 B).
How do I convert bytes to bits?
Multiply the number of bytes by 8. For example, 10 B × 8 = 80 bit. To convert back, multiply by 0.125.
What is 10 B in bits?
10 B = 80 bit.
What is 100 B in bits?
100 B = 800 bit.
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.
