How to Convert Hertz to Megahertz

1 hertz = 1 × 10-6 megahertz

Megahertz = Hertz × 1 × 10-6

Example: 428357 Hz × 1 × 10-6 = 0.42836 MHz

Reverse Conversion

To convert megahertz back to hertz:

  • Remember, 1 megahertz equals 1000000 hertz.
  • To convert 0.42836 MHz to Hz, multiply 0.42836 x 1000000, resulting in 428360 Hz.

428357 Hz is also equal to:

  • 428.36 kilohertz
  • 0.00042836 gigahertz
  • 2.5701 × 107 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
