How to Convert Megahertz to Hertz

1 megahertz = 1000000 hertz

Hertz = Megahertz × 1000000

Example: 1 MHz × 1000000 = 1000000 Hz

Reverse Conversion

To convert hertz back to megahertz:

  • Remember, 1 hertz equals 1 × 10-6 megahertz.
  • To convert 1000000 Hz to MHz, multiply 1000000 x 1 × 10-6, resulting in 1 MHz.

Definition of Megahertz

Megahertz: Radio and Computing Frequency Unit

The megahertz (symbol: MHz) is a unit of frequency equal to one million hertz (10⁶ Hz). It is the standard unit for describing radio broadcast frequencies, early computer processor speeds, and many wireless communication standards.

Conversions to Other Units of Measurement:

  1. Hertz (Hz): 1 MHz equals exactly 1,000,000 Hz. FM radio stations broadcast in the 87.5-108 MHz range.
  2. Kilohertz (kHz): 1 MHz equals exactly 1,000 kHz. This is used when converting between AM radio (kHz) and FM radio (MHz) frequency bands.
  3. Gigahertz (GHz): 1 MHz equals 0.001 GHz. Modern processors operate in the GHz range, while earlier CPUs were specified in MHz.
  4. Revolutions per Minute (rpm): 1 MHz equals 60,000,000 rpm. While no mechanical device spins this fast, the conversion illustrates the vast difference between electromagnetic and mechanical oscillations.

The megahertz was the primary unit for describing computer processor speeds from the 1970s through the early 2000s before gigahertz became common. It remains widely used for radio frequency engineering.

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:

  1. Kilohertz (kHz): 1 Hz equals 0.001 kHz. Kilohertz is commonly used for audio frequencies and AM radio broadcasting.
  2. Megahertz (MHz): 1 Hz equals 0.000001 MHz. Megahertz is used for FM radio and television broadcasting frequencies.
  3. Gigahertz (GHz): 1 Hz equals 10⁻⁹ GHz. Gigahertz is used for microwave frequencies, Wi-Fi, and modern processor clock speeds.
  4. Revolutions per Minute (rpm): 1 Hz equals 60 rpm. This conversion is fundamental in mechanical and electrical engineering for relating rotational speed to frequency.
  5. 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 Megahertz

Wi-Fi operates primarily in two frequency bands: 2.4 GHz (2,400 MHz) and 5 GHz (5,000 MHz). The 2.4 GHz band offers better range but slower speeds, while 5 GHz provides faster data rates at shorter distances. Newer Wi-Fi 6E adds the 6 GHz band.

The first personal computers in the late 1970s had processors running at just 1-4 MHz. By comparison, a modern smartphone processor runs at 2,000-3,000 MHz — roughly a thousand times faster.

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 megahertz?

One megahertz equals 1000000 hertz. To convert, multiply the megahertz value by 1000000. For the reverse, divide the hertz value by 1000000 (or multiply by 1 × 10-6).

What is 10 megahertz in hertz?

10 megahertz = 10000000 hertz. This is one of the most commonly searched conversions for this pair.

How precise is the megahertz-to-hertz conversion?

The factor 1000000 is accurate to 6 significant figures, derived from international measurement standards. Our calculator uses full precision internally.
