Kilohertz to Hertz Converter
How to Convert Kilohertz to Hertz
1 kilohertz = 1000 hertz
Hertz = Kilohertz × 1000
Example: 1 kHz × 1000 = 1000 Hz
Reverse Conversion
To convert hertz back to kilohertz:
- Remember, 1 hertz equals 0.001 kilohertz.
- To convert 1000 Hz to kHz, multiply
1000 x 0.001, resulting in1 kHz.

Definition of Kilohertz
Kilohertz: Audio and Radio Frequency Unit
The kilohertz (symbol: kHz) is a unit of frequency equal to 1,000 hertz. It is widely used in audio engineering, radio communications, and electronics. Human hearing ranges from about 0.02 kHz to 20 kHz, making the kilohertz a natural unit for describing audible frequencies.
Conversions to Other Units of Measurement:
- Hertz (Hz): 1 kHz equals exactly 1,000 Hz. AM radio stations in the US broadcast in the 535-1705 kHz range.
- Megahertz (MHz): 1 kHz equals 0.001 MHz. This conversion is used when comparing audio frequencies with radio spectrum allocations.
- Revolutions per Minute (rpm): 1 kHz equals 60,000 rpm. High-speed turbines and dental drills operate at frequencies in the kilohertz range.
- Radians per Second (rad/s): 1 kHz equals approximately 6,283.2 rad/s. Used in signal processing and control systems analysis.
The kilohertz is the standard unit for describing audio sampling rates (44.1 kHz for CD quality, 48 kHz for professional audio) and ultrasonic frequencies used in medical imaging.

Definition of Hertz
Hertz: The SI Unit of Frequency
The hertz (symbol: Hz) is the SI unit of frequency, defined as one cycle per second. It is named after Heinrich Rudolf Hertz, who first conclusively proved the existence of electromagnetic waves in 1887. One hertz means that an event repeats once per second.
Conversions to Other Units of Measurement:
- Kilohertz (kHz): 1 Hz equals 0.001 kHz. Kilohertz is commonly used for audio frequencies and AM radio broadcasting.
- Megahertz (MHz): 1 Hz equals 0.000001 MHz. Megahertz is used for FM radio and television broadcasting frequencies.
- Gigahertz (GHz): 1 Hz equals 10⁻⁹ GHz. Gigahertz is used for microwave frequencies, Wi-Fi, and modern processor clock speeds.
- Revolutions per Minute (rpm): 1 Hz equals 60 rpm. This conversion is fundamental in mechanical and electrical engineering for relating rotational speed to frequency.
- Radians per Second (rad/s): 1 Hz equals 2π rad/s (approximately 6.2832 rad/s). This angular frequency is essential in physics and signal processing.
The hertz is fundamental across science and engineering, from describing sound pitch and radio waves to processor clock speeds and power grid frequencies.

About the Kilohertz
The standard audio CD uses a sampling rate of 44.1 kHz, chosen because it is slightly more than twice the upper limit of human hearing (20 kHz), satisfying the Nyquist-Shannon sampling theorem. Professional audio typically uses 48 kHz or 96 kHz.
AM radio stations broadcast in the kilohertz range (535-1705 kHz in the Americas). The lower frequency allows AM signals to travel much farther than FM, especially at night when they can bounce off the ionosphere.
About the Hertz
The hertz is named after Heinrich Hertz (1857-1894), who was the first to conclusively demonstrate the existence of electromagnetic waves predicted by James Clerk Maxwell's equations. Hertz's experiments in 1887 used a spark gap transmitter operating at about 50 MHz.
Power grids worldwide operate at either 50 Hz (Europe, Asia, Africa, most of South America) or 60 Hz (North America, parts of South America and Asia). This frequency determines the "hum" you sometimes hear from electrical equipment.
Frequently Asked Questions
How many hertz are in one kilohertz?
One kilohertz equals 1000 hertz. To convert, multiply the kilohertz value by 1000. For the reverse, divide the hertz value by 1000 (or multiply by 0.001).
What is 10 kilohertz in hertz?
10 kilohertz = 10000 hertz. This is one of the most commonly searched conversions for this pair.
Is the kilohertz-to-hertz conversion exact?
Yes. The factor 1000 is exact by international definition, not an approximation. Any imprecision comes only from the original measurement, not the conversion.
