Megahertz (MHz) to Hertz (Hz) Conversion Calculator and Table

Megahertz (MHz) and Hertz (Hz) are used to measure frequency, and their conversions are simple and straightforward - one just has to remember that "M" stands for "Mega," which is, according to the SI prefixes table, 106 (one million) of the main value.

How To Convert Megahertz (MHz) to Hertz (Hz)

"M" stands for "million" and means "one million." Thus, one Megahertz equals 1000000 Hertz:

1 MHz = 1000000 Hz = 106 Hz

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

f(MHz) = 15.34 MHz = 15.34 * 1000000Hz = 15340000 Hz


  • 10 MHz to Hz → 10 MHz = 10 * 1000000 Hz = 10000000 Hz
  • 20 MHz to Hz → 20 MHz = 20 * 1000000 Hz = 20000000 Hz
  • 100 MHz to Hz → 100 MHz = 100 * 1000000 Hz = 100000000 Hz

A Brief History of Hertz

The hertz (Hz), a unit of frequency in the International System of Units (SI), has a significant place in the history of science and technology. Named after Heinrich Hertz, a German physicist who made large contributions to the field of electromagnetism, the hertz has become the standard unit for measuring the frequency of periodic events, particularly in the fields of physics and engineering.

The Inception of Hertz

The hertz unit was named in honor of Heinrich Hertz, whose experiments in the late 19th century proved the existence of electromagnetic waves, thus validating James Clerk Maxwell's earlier theories. Hertz's work laid the foundation for the development of radio, television, radar, and numerous other technologies that rely on electromagnetic waves.

In 1930, the unit of frequency, previously known as cycles per second, was officially renamed the "hertz" in his honor. This renaming occurred at the International Electrotechnical Commission (IEC) in Paris, symbolizing the global recognition of Hertz's contributions.

Defining the Hertz

The hertz quantifies the number of cycles per second of any periodic event. For example, if a guitar string vibrates 440 times per second, its frequency is 440 Hz. This simple yet fundamental concept is crucial in various scientific and technological domains, from acoustics to electronics.

Applications and Implications

The hertz finds its application in several areas:

  • Electromagnetic Waves: Radio waves, microwaves, and light waves are measured in hertz. For instance, FM radio stations broadcast in the megahertz (MHz) range.
  • Sound Waves: The pitch of a sound is expressed in hertz. Human hearing typically ranges from 20 Hz to 20,000 Hz.
  • Computing: The processing speed of a computer's CPU is often measured in gigahertz (GHz).

Larger and Smaller Units

The hertz is a versatile unit, scalable to fit various magnitudes:

  • Kilohertz (kHz): One thousand hertz, commonly used in radio frequency.
  • Megahertz (MHz): One million hertz, a standard unit for broadcasting frequencies.
  • Gigahertz (GHz): One billion hertz, typically used to describe the clock speed of computer processors.

The hertz, deriving its name from Heinrich Hertz's groundbreaking work, is a fundamental unit in measuring frequency.

Its widespread use across different fields, from audio engineering to telecommunications, highlights its importance in understanding and manipulating various forms of waves and periodic phenomena.
