# Kilobytes to bytes

**1 kilobyte in bytes: 1 kB = 1,000 B**

B = kB × 1,000

To convert kilobytes to bytes, multiply by 1,000. The table below gives the values people look up most often, and the converter works for any number.

| 1 kB | 1,000 |
| 2 kB | 2,000 |
| 3 kB | 3,000 |
| 4 kB | 4,000 |
| 5 kB | 5,000 |
| 10 kB | 10,000 |
| 15 kB | 15,000 |
| 20 kB | 20,000 |
| 25 kB | 25,000 |
| 30 kB | 30,000 |
| 40 kB | 40,000 |
| 50 kB | 50,000 |
| 75 kB | 75,000 |
| 100 kB | 100,000 |
| 250 kB | 250,000 |
| 500 kB | 500,000 |
| 1,000 kB | 1,000,000 |

## How the conversion works

The relationship is B = kB × 1,000. Both units measure data, so the conversion is a fixed factor that never changes.

> Kilobyte: Decimal: 1,000 bytes.

## Common questions

### How many bytes are in one kilobyte?

One kilobyte equals 1,000 bytes. B = kB × 1,000.

### How do you convert kilobytes to bytes?

Use B = kB × 1,000. So 10 kB is 10,000 B.

### How many kilobytes are in one byte?

One byte equals 0.001 kilobytes, which is the reverse of the conversion above.

### Is there more than one kind of kilobyte?

Decimal: 1,000 bytes.
