bits to bytes reference
| bits | bytes |
|---|---|
| 1 bit | 0.125 B |
| 2 bit | 0.25 B |
| 5 bit | 0.625 B |
| 10 bit | 1.25 B |
| 25 bit | 3.125 B |
| 50 bit | 6.25 B |
| 100 bit | 12.5 B |
The conversion factor
One bit is 0.125 bytes. So to convert, multiply your figure in bits by 0.125. To go the other way, multiply bytes by 8, or use the bytes to bits converter.
Doing it in your head
For a quick estimate, round the factor: roughly "divide by 8". Use the exact converter above when the number matters.
Where this conversion comes up
Storage and download sizes, data caps, and the decimal-vs-binary gap that makes a “1 TB” drive show as about 931 GiB.
See the common unit conversions cheat sheet for the factors worth memorising.

Frequently asked questions
How many bytes are in a bit?
1 bit = 0.125 bytes.
What is the formula to convert bits to bytes?
Multiply the number of bits by 0.125. To go back the other way, multiply bytes by 8.
What is 10 bits in bytes?
10 bits = 1.25 bytes. The reference table below lists more common values.
Is this converter accurate?
It uses the internationally defined conversion factors and computes at full floating-point precision, then rounds only the displayed result. For everyday purposes it is exact; for legal, engineering or scientific work, confirm the required number of significant figures.
Does it work offline?
Yes. The conversion runs in your browser with no server call, so it keeps working with no connection, and nothing you enter is uploaded.
