How to convert bits to bytes

B = b ÷ 8

Example: convert 8 bits to bytes.
8 b ÷ 8 = 1 B

The same relationship in reverse: 1 byte = 8 bits, so you can also multiply by 0.125. Need the other direction? Use the bytes to bits converter.

You will typically need this conversion for networking, encryption key sizes and programming.

About the units

Bit (b)

A single binary digit, 0 or 1 — the smallest unit of digital information. Eight bits make one byte.

Byte (B)

Eight bits. One byte stores one ASCII character.

Frequently asked questions

How many bytes are in a bit?

1 bit = 0.125 bytes. Going the other way, 1 byte = 8 bits.

How do I convert bits to bytes?

To convert bits to bytes, divide by 8. The formula is B = b ÷ 8.

What is 8 b in B?

8 bits is 1 bytes (8 b ÷ 8 = 1 B).
