# Bytes to bits

**1 byte in bits: 1 B = 8 bit**

bit = B × 8

To convert bytes to bits, multiply by 8. The table below gives the values people look up most often, and the converter works for any number.

## Bytes to bits table

*Common byte values converted to bits.*

| Bytes | Bits |
| --- | --- |
| 1 B | 8 |
| 2 B | 16 |
| 3 B | 24 |
| 4 B | 32 |
| 5 B | 40 |
| 10 B | 80 |
| 15 B | 120 |
| 20 B | 160 |
| 25 B | 200 |
| 30 B | 240 |
| 40 B | 320 |
| 50 B | 400 |
| 75 B | 600 |
| 100 B | 800 |
| 250 B | 2,000 |
| 500 B | 4,000 |
| 1,000 B | 8,000 |

## How the conversion works

The relationship is bit = B × 8. Both units measure data, so the conversion is a fixed factor that never changes.

## Common questions

### How many bits are in one byte?

One byte equals 8 bits. bit = B × 8.

### How do you convert bytes to bits?

Use bit = B × 8. So 10 B is 80 bit.

### How many bytes are in one bit?

One bit equals 0.125 bytes, which is the reverse of the conversion above.
