# Bits to bytes

**1 bit in bytes: 1 bit = 0.125 B**

B = bit × 1/8

To convert bits to bytes, multiply by 0.125. The table below gives the values people look up most often, and the converter works for any number.

## Bits to bytes table

*Common bit values converted to bytes.*

| Bits | Bytes |
| --- | --- |
| 1 bit | 0.125 |
| 2 bit | 0.25 |
| 3 bit | 0.375 |
| 4 bit | 0.5 |
| 5 bit | 0.625 |
| 10 bit | 1.25 |
| 15 bit | 1.875 |
| 20 bit | 2.5 |
| 25 bit | 3.125 |
| 30 bit | 3.75 |
| 40 bit | 5 |
| 50 bit | 6.25 |
| 75 bit | 9.375 |
| 100 bit | 12.5 |
| 250 bit | 31.25 |
| 500 bit | 62.5 |
| 1,000 bit | 125 |

## How the conversion works

The relationship is B = bit × 1/8. Both units measure data, so the conversion is a fixed factor that never changes.

## Common questions

### How many bytes are in one bit?

One bit equals 0.125 bytes. B = bit × 1/8.

### How do you convert bits to bytes?

Use B = bit × 1/8. So 10 bit is 1.25 B.

### How many bits are in one byte?

One byte equals 8 bits, which is the reverse of the conversion above.
