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.

1 MHz equals 1,000,000 Hz (one million hertz). This frequency falls in the AM radio broadcast band and is sometimes used as a standard reference in electronics.

1 MHz is also equal to:

  • 1000 kilohertz
  • 0.001 gigahertz
  • 6 × 107 revolution per minute
About these units

Megahertz: SI decimal multiple of hertz; 1 MHz = 1,000,000 Hz = 10⁶ Hz

Hertz: SI unit of frequency; one cycle (or event) per second. Symbol: Hz = s⁻¹

Frequently Asked Questions

How much is 1 megahertz in hertz?

1 megahertz equals 1000000 hertz. This is calculated by multiplying 1 by the conversion factor 1000000.

What does 1 megahertz look like in hertz?

1 megahertz (1000000 hertz) is HF band — shortwave radio and amateur radio.

How do you calculate 1 megahertz to hertz?

Multiply 1 by the conversion factor 1000000. The calculation is 1 × 1000000 = 1000000 hertz. This factor is defined by international measurement standards.
