How to convert Hertz to Kilohertz
To convert hertz to kilohertz, multiply by 0.001. One hertz equals 0.001 kHz, and one kilohertz equals 1,000 Hz.
- Take the value in hertz — for example 7.5 Hz.
- Multiply by 0.001 (the number of kilohertz in one hertz).
- 7.5 × 0.001 = 0.0075 kHz.
Shortcut: the factor is a power of ten, so just move the decimal point 3 places to the left.

About converting Hertz to Kilohertz
Hertz (Hz) and Kilohertz (kHz) are both units of frequency. The exact factor is 1 Hz = 0.001 kHz, so multiply by 0.001 to go from hertz to kilohertz (or divide to go back).
The conversion runs entirely in your browser. Need the reverse? Use the Kilohertz to Hertz converter, or the full unit converter for every unit at once.
Real-world frequency in hertz and kilohertz
| Example | Hertz | Kilohertz |
|---|---|---|
| Mains electricity in Europe & India | 50 Hz | 0.05 kHz |
| Mains electricity in North America | 60 Hz | 0.06 kHz |
| Concert pitch A4 (ISO 16) | 440 Hz | 0.44 kHz |
| The upper limit of human hearing | ≈ 20,000 Hz | ≈ 20 kHz |
“≈” marks typical values; the rest are defined or measured figures.
