How to Convert Megahertz to Hertz

1 megahertz = 1000000 hertz

Hertz = Megahertz × 1000000

Example: 657 MHz × 1000000 = 6.57 × 108 Hz

Reverse Conversion

To convert hertz back to megahertz:

  • Remember, 1 hertz equals 1 × 10-6 megahertz.
  • To convert 6.57 × 108 Hz to MHz, multiply 6.57 × 108 x 1 × 10-6, resulting in 657 MHz.

657 MHz is also equal to:

  • 657000 kilohertz
  • 0.657 gigahertz
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
