hertz to kilohertz
Convert hertz (Hz) to kilohertz (kHz). Use an editable frequency converter, conversion formula, and reference table.
1 Hz = 0.001 kHz
Conversion formula
One hertz equals 0.001 kilohertz. Multiply your value in hertz by this factor to get kilohertz. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 hertz:5 × 0.001 = 0.005 kHz
Conversion table
| hertz (Hz) | kilohertz (kHz) |

| 1 | 0.001 |
| 2 | 0.002 |
| 5 | 0.005 |
| 10 | 0.01 |
| 25 | 0.025 |
| 50 | 0.05 |
| 100 | 0.1 |
| 1000 | 1 |
About these measurements
Frequency measures cycles per second.
The base reference used here is the hertz. One hertz is 1 base units; one kilohertz is 1,000 base units.
Important distinctions
Frequency is the reciprocal of period, not angular velocity.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert Hz to kHz?
Multiply the quantity in Hz by 0.001. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the kilohertz to hertz converter.
