How many hertz are in one kilohertz?

There are 1,000 hertz in 1 kilohertz.

How do you convert hertz to kilohertz?

Multiply the number of hertz by 0.001 — or use the formula kHz = Hz ÷ 1,000.

What is 6 hertz in kilohertz?

6 hertz is 0.006 kilohertz. 6 ÷ 1,000 = 0.006 kilohertz.

Is the hertz to kilohertz conversion exact?

Yes. The relationship is fixed by definition, so 0.001 is an exact conversion factor — only the displayed result is rounded.

What is 1 hertz in kilohertz?

1 hertz is equal to exactly 0.001 kilohertz.

1 ÷ 1,000 = 0.001 kilohertz

Amount

Result0.001

1 hertz = 0.001 kilohertz

Hertz to Kilohertz formula

kHz = Hz ÷ 1,000

The hertz to kilohertz conversion factor is 0.001, which is exact by definition. 1 hertz = 0.001 kilohertz, and 1 kilohertz = 1,000 hertz.

Worked examples

2 hertz = 0.002 kilohertz — 2 ÷ 1,000 = 0.002 kilohertz
6 hertz = 0.006 kilohertz — 6 ÷ 1,000 = 0.006 kilohertz
10 hertz = 0.01 kilohertz — 10 ÷ 1,000 = 0.01 kilohertz

When you need to convert hertz to kilohertz

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 hertz = 0.001 kilohertz, the answer should be smaller 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

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.
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.
