Convert bytes to bits
Byte (B) to bit (bit). One byte equals 8 bits.
Formula
Byte to bit conversion table
| Bytes | Bits | Bits | Bytes |
|---|---|---|---|
| 1 B | 8 bit | 1 bit | 0.125 B |
| 2 B | 16 bit | 2 bit | 0.25 B |
| 3 B | 24 bit | 3 bit | 0.375 B |
| 5 B | 40 bit | 5 bit | 0.625 B |
| 10 B | 80 bit | 10 bit | 1.25 B |
| 20 B | 160 bit | 20 bit | 2.5 B |
| 50 B | 400 bit | 50 bit | 6.25 B |
| 100 B | 800 bit | 100 bit | 12.5 B |
| 500 B | 4000 bit | 500 bit | 62.5 B |
| 1000 B | 8000 bit | 1000 bit | 125 B |
To convert bytes to bits, multiply the number of bytes by 8. One byte equals 8 bits, and one bit equals 0.125 bytes, so the relationship is fixed and exact. As a worked example, 10 B comes to 80 bit. Enter your own figure in the converter above to get an instant answer, or use the swap button to flip the direction. This is a digital storage conversion, and like every tool on UnitGlide it runs locally in your browser with no account or upload required. The table further down shows a range of common byte values already worked out in bits, plus the reverse bit to byte direction, which is handy for quick reference or double-checking a result by hand.
Frequently asked questions
How many bits are in a byte?
One byte equals 8 bits. The ratio is constant, so you can multiply any number of bytes by 8 to get bits.
What is the formula to convert bytes to bits?
Use bits = bytes × 8. UnitGlide applies this exact formula for every value, so results stay accurate across the whole range.
How do I convert bits back to bytes?
Go the other way by using one bit equals 0.125 bytes. You can also press the swap button in the converter above to flip the direction in one click.
Is this byte to bit converter accurate?
Yes. It uses internationally defined SI conversion factors, as maintained by the BIPM, and all math runs in your browser so nothing is rounded away on a server. For everyday use the displayed precision is more than enough.
