Bit to Byte Converter (bit to B)

1 bit equals 0.125 bytes — divide bits by 8 (or multiply by 0.125) to convert. Because a byte is made of 8 bits, one bit is one-eighth of a byte.

The formula

To convert bits to bytes, multiply by 0.125:

bytes = bits × 0.125

For example, 10 bit × 0.125 = 1.25 B. To reverse it, divide by 0.125 (or multiply by 8).

Where this conversion is used

Networking and data rates are usually measured in bits (megabits per second), while file sizes and storage are measured in bytes. Converting bits to bytes is the key step when working out how fast a file will actually download or how a stated link speed maps to real throughput.

FAQ

How many bytes are in a bit?

One bit equals 0.125 bytes — one-eighth of a byte. So 8 bits make exactly 1 byte.

How do I convert bytes back to bits?

Divide by 0.125, or multiply by 8. So 1 byte is 8 bits and 4 bytes is 32 bits.

Is the conversion exact?

Yes. A byte is defined as exactly 8 bits, so 1 bit = 0.125 byte is exact.

Is this converter free and private?

Yes. It runs entirely in your browser — nothing is uploaded or stored. It is free, needs no sign-up and works offline once loaded.
