How to Convert Kilohertz to Hertz
Formula
To convert Kilohertz (kHz) to Hertz (Hz): multiply by 1000
Step-by-Step
- Start with your value in Kilohertz (kHz).
- Multiply by 1000 to perform the conversion.
- The result is your value expressed in Hertz (Hz).
Conversion Factor
1 kHz = 1000 Hz
Reverse Factor
1 Hz = 0.001 kHz
Worked Example
Convert 25 Kilohertz to Hertz: 25 kHz = 25000 Hz
About Kilohertz (kHz)
A frequency unit equal to 1,000 Hz. Kilohertz is the native band for AM radio (530–1,700 kHz), audio sampling rates (44.1 kHz for CD audio, 48 kHz for video standard), ultrasound in medical imaging (up to 50 MHz), and low-frequency RF applications such as submarine communication and RFID. Audio engineers and radio designers work in kHz daily.
About Hertz (Hz)
The SI unit of frequency equal to one cycle per second (1 Hz = 1 s⁻¹). Named after Heinrich Hertz, who first demonstrated electromagnetic waves in the 1880s. Hertz is the universal unit for any periodic phenomenon: display refresh rates (60 Hz, 120 Hz, 144 Hz), mains power (50 or 60 Hz), heart rate (~1 Hz at rest), sound wave pitch (human hearing: 20 Hz to 20 kHz), and vibration analysis of rotating machinery.

Frequently Asked Questions
How do I convert Kilohertz to Hertz?
A frequency unit equal to 1,000 Hz. To convert Kilohertz to Hertz, multiply by 1000. For example, 25 kHz equals 25000 Hz.
How many Hertz are in 1 Kilohertz?
There are 1000 Hertz in 1 Kilohertz.
How many Kilohertz are in 1 Hertz?
There are 0.001 Kilohertz in 1 Hertz.
What is the formula for Kilohertz to Hertz conversion?
The formula is: multiply by 1000. This means 1 kHz = 1000 Hz.
Is a Kilohertz bigger than a Hertz?
No. One Kilohertz is smaller than one Hertz because 1 kHz equals 1000 Hz, which is greater than 1.
When do you need to convert between Kilohertz and Hertz?
The SI unit of frequency equal to one cycle per second (1 Hz = 1 s⁻¹).
