# Hertz to kilohertz

**1 hertz in kilohertz: 1 Hz = 0.001 kHz**

kHz = Hz × 0.001

To convert hertz to kilohertz, multiply by 0.001. The table below gives the values people look up most often, and the converter works for any number.

## Hertz to kilohertz table

*Common hertz values converted to kilohertz.*

| Hertz | Kilohertz |
| --- | --- |
| 1 Hz | 0.001 |
| 2 Hz | 0.002 |
| 3 Hz | 0.003 |
| 4 Hz | 0.004 |
| 5 Hz | 0.005 |
| 10 Hz | 0.01 |
| 15 Hz | 0.015 |
| 20 Hz | 0.02 |
| 25 Hz | 0.025 |
| 30 Hz | 0.03 |
| 40 Hz | 0.04 |
| 50 Hz | 0.05 |
| 75 Hz | 0.075 |
| 100 Hz | 0.1 |
| 250 Hz | 0.25 |
| 500 Hz | 0.5 |
| 1,000 Hz | 1 |

## How the conversion works

The relationship is kHz = Hz × 0.001. Both units measure frequency, so the conversion is a fixed factor that never changes.

## Common questions

### How many kilohertz are in one hertz?

One hertz equals 0.001 kilohertz. kHz = Hz × 0.001.

### How do you convert hertz to kilohertz?

Use kHz = Hz × 0.001. So 10 Hz is 0.01 kHz.

### How many hertz are in one kilohertz?

One kilohertz equals 1,000 hertz, which is the reverse of the conversion above.
