How to Convert Hertz to Megahertz

1 hertz = 1 × 10-6 megahertz

Megahertz = Hertz × 1 × 10-6

Example: 1689 Hz × 1 × 10-6 = 0.001689 MHz

Reverse Conversion

To convert megahertz back to hertz:

  • Remember, 1 megahertz equals 1000000 hertz.
  • To convert 0.001689 MHz to Hz, multiply 0.001689 x 1000000, resulting in 1689 Hz.

1689 Hz is also equal to:

  • 1.689 kilohertz
  • 101340 revolution per minute
About these units

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

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