Kilohertz (kHz) to Hertz (Hz) Conversion Calculator and Table

Kilohertz (kHz) and Hertz (Hz) are used to measure frequency, and their conversions are simple and straightforward - one just has to remember that "k" stands for "kilo," which is, according to the SI prefixes table, 103 (one thousand) of the main value.

How To Convert Kilohertz (kHz) to Hertz (Hz)

"k" stands for "kilo" and means "one thousand." Thus, one kilohertz equals 1000 Hertz:

1 kHz = 1000Hz

For example, if You want to convert 15.34 kHz to Hertz, You can write:

f(kHz) = 15.34 kHz = 15.34 * 1000Hz = 15340 kHz


  • 10 kHz to Hz → 10 kHz = 10 * 1000 Hz = 10000 Hz
  • 20 kHz to Hz → 20 kHz = 20 * 1000 Hz = 20000 Hz
  • 100 kHz to Hz → 100 kHz = 100 * 1000 Hz = 100000 Hz

A Brief Intro to Hertz

The hertz (Hz) is the unit of frequency in the International System of Units (SI) and is defined as one cycle per second.

This unit is named after Heinrich Hertz, a German physicist who made significant contributions to the understanding of electromagnetic wave propagation. Hertz's experiments in the late 19th century confirmed the existence of electromagnetic waves, predicted by James Clerk Maxwell's equations. In 1930, the unit was established to honor Hertz's groundbreaking work.

Before the introduction of hertz as a unit, the frequency was commonly referred to in terms of cycles per second or simply "per second." The adoption of hertz as a standard unit brought uniformity and clarity, especially in the fields of physics and engineering.

The hertz is used to measure a wide range of frequencies, from sub-audible to visible light and beyond. It is a crucial unit in the study and application of electromagnetic spectrum, sound waves, and signal processing.

Examples of frequencies measured in hertz include:

AC (Alternating Current) Frequencies:

  • North America: 60 Hz
  • Europe and most of Asia: 50 Hz

Radio Wave Frequencies:

  • AM Radio: 540 to 1600 kHz (kilohertz)
  • FM Radio: 88 to 108 MHz (megahertz)

Processor Clock Speeds:

  • Early Microprocessors (1970s): 1 to 2 MHz
  • Modern Processors (2020s): 1 to 5 GHz (gigahertz), with some reaching higher frequencies

Other Applications:

  • Human Audible Range: 20 Hz to 20 kHz
  • Medical Ultrasound: Typically 2 to 18 MHz
  • Wi-Fi Signals: 2.4 GHz or 5 GHz

The versatility of the hertz in measuring such a wide range of phenomena highlights its importance across different scientific and technological domains. From powering electrical grids to transmitting data wirelessly, the concept of frequency, measured in hertz, is fundamental to modern society.
