What is 1 kilohertz in hertz?
1 kilohertz is equal to exactly 1,000 hertz.
1 × 1,000 = 1,000 hertz
Result
1 kilohertz = 1,000 hertz
Kilohertz to Hertz formula
Hz = kHz × 1,000
The kilohertz to hertz conversion factor is 1,000, which is exact by definition. 1 kilohertz = 1,000 hertz, and 1 hertz = 0.001 kilohertz.
Worked examples
- 2 kilohertz = 2,000 hertz — 2 × 1,000 = 2,000 hertz
- 6 kilohertz = 6,000 hertz — 6 × 1,000 = 6,000 hertz
- 10 kilohertz = 10,000 hertz — 10 × 1,000 = 10,000 hertz

When you need to convert kilohertz to hertz
- Comparing specifications written for a different market.
- Checking a figure quoted in an unfamiliar unit before acting on it.
- Converting values consistently across a spreadsheet, report or shopping list.
Common mistakes to avoid
- Dividing when you should multiply. Because 1 kilohertz = 1,000 hertz, the answer should be larger than the number you started with.
- Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.
How precise does the answer need to be?
Round only at the end, and only to the precision your task actually needs. The converter above keeps full double precision internally and rounds for display.
How these units are defined
- Kilohertz (kHz): One thousand cycles per second. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
- Hertz (Hz): One cycle per second; the SI unit of frequency. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
