How to Convert Megahertz to Hertz

1 megahertz = 1000000 hertz

Hertz = Megahertz × 1000000

Example: 100 MHz × 1000000 = 1 × 108 Hz

Reverse Conversion

To convert hertz back to megahertz:

  • Remember, 1 hertz equals 1 × 10-6 megahertz.
  • To convert 1 × 108 Hz to MHz, multiply 1 × 108 x 1 × 10-6, resulting in 100 MHz.

100 MHz equals 100,000,000 Hz — within the FM radio broadcast band (87.5-108 MHz). A "100 MHz" station transmits at one hundred million cycles per second.

100 MHz is also equal to:

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 100 megahertz in hertz?

100 megahertz equals 1 × 10⁸ hertz. This is calculated by multiplying 100 by the conversion factor 1000000.

What does 100 megahertz look like in hertz?

100 megahertz (1 × 10⁸ hertz) is VHF band — FM radio (88-108 MHz), TV, aviation communications.

How do you calculate 100 megahertz to hertz?

Multiply 100 by the conversion factor 1000000. The calculation is 100 × 1000000 = 1 × 10⁸ hertz. This factor is defined by international measurement standards.
