Bytes to Bits
1 byte = 8 bits. To convert bytes (B) to bits (b), multiply by 8.
Converter
How to convert bytes to bits
b = B × 8 Example: convert 8 bytes to bits.
8 B × 8 = 64 b
The same relationship in reverse: 1 bit = 0.125 bytes, so you can also divide by 0.125. Need the other direction? Use the bits to bytes converter.
You will typically need this conversion for networking, encryption key sizes and programming.

About the units
Byte (B)
Eight bits. One byte stores one ASCII character.
Bit (b)
A single binary digit, 0 or 1 — the smallest unit of digital information. Eight bits make one byte.
Frequently asked questions
How many bits are in a byte?
1 byte = 8 bits. Going the other way, 1 bit = 0.125 bytes.
How do I convert bytes to bits?
To convert bytes to bits, multiply by 8. The formula is b = B × 8.
What is 8 B in b?
8 bytes is 64 bits (8 B × 8 = 64 b).
