Bytes to Bits Converter
Useful in programming, networking and data encoding, where sizes switch between bytes and bits.
1 B = 8 bit
bits
1 B = 8 bit
How to convert bytes to bits
Multiply the number of bytes by 8.
Formula
bit = B × 8
Examples
- 4 B × 8 = 32 bit
- 256 B × 8 = 2,048 bit
- 1,500 B × 8 = 12,000 bit

About bytes
A byte is 8 bits. File sizes, memory and storage capacity are all measured in bytes and their multiples.
About bits
A bit is the smallest unit of digital information: a single 0 or 1. Internet and network speeds are measured in bits per second, such as 100 Mbps.
Frequently asked questions
How many bits are in one byte?
One byte equals 8 bits.
How do I convert bytes to bits?
Multiply the number of bytes by 8. For example: 256 B × 8 = 2,048 bit.
How many bytes are in one bit?
One bit equals 0.125 bytes.
Is the B to bit conversion exact?
Yes. The factor follows directly from the official definitions of both units, so the only rounding is in how many decimals are displayed.
