Convert Bit to Byte

1 bit = 0.125 byte (B). For example, 10 bit = 1.25 byte and 100 bit = 12.5 byte. Type any value below to convert bit to byte both ways — it runs entirely in your browser.

Bit to Byte conversion formula

To convert bit to byte, multiply by 0.125:

byte = bit × 0.125

Going the other way, 1 byte = 8 bit, so bit = byte × 8.

About bit and byte

Bit: A bit is a single binary digit (0 or 1). 8 bits = 1 byte.

Byte: A byte is 8 bits — the basic addressable unit of computer storage.

This converter uses the decimal (SI) convention for KB/MB/GB/TB (1 KB = 1,000 bytes), as used by storage manufacturers and networks. The binary units — KiB, MiB, GiB (1 KiB = 1,024 bytes) — are listed separately, because operating systems often label binary sizes with the decimal names.

Frequently asked questions

How many byte are in 1 bit?
1 bit = 0.125 byte (B).
How do I convert bit to byte?
Multiply the number of bit by 0.125. For example, 10 bit = 10 × 0.125 = 1.25 byte.
How many bit are in 1 byte?
1 byte = 8 bit.
Which is bigger, bit or byte?
1 byte equals 8 bit, so a byte is the larger unit.
