How to convert kilohertz to hertz

Multiply the number of kilohertz by 1,000 to get hertz: Hz = kHz × 1,000.

Example: 5 kHz = 5,000 Hz.

The kilohertz (kHz) and the hertz (Hz) are both units of frequency. Need the opposite direction? Use the Hz to kHz converter.

Metric and imperial units

The metric system (SI) is used by almost every country and by science worldwide. Its units scale by powers of ten – 1 kilometer is 1,000 meters, 1 meter is 100 centimeters – which makes conversions inside the system easy. The imperial and US customary systems (inches, feet, pounds, gallons) are still used daily in the United States and partly in the UK.

Since 1959 the inch has been defined as exactly 2.54 centimeters and the pound as exactly 0.45359237 kilograms, so conversions between the two systems are exact. Note that a US gallon (3.785 L) and an imperial gallon (4.546 L) are different – choose the right one above.

This converter covers 18 categories and 106 units: length, weight, temperature, volume, area, speed, time, data, energy, pressure, power, angle, force, torque, frequency, flow rate, illuminance, density.

Frequently asked questions

How many hertz are in a kilohertz?

1 kilohertz = 1,000 hertz.

How do I convert kilohertz to hertz?

Use the formula Hz = kHz × 1,000. For example, 5 kHz = 5,000 Hz.

How do I convert hertz back to kilohertz?

1 hertz = 0.001 kilohertz. Use the Hz to kHz converter linked on this page.

Are these conversions exact?

Yes – all factors use the internationally defined values (for example 1 inch = 2.54 cm exactly, 1 pound = 0.45359237 kg exactly). Results are rounded to 8 significant digits for display.
