How to Convert Hertz to Megahertz

1 hertz = 1 × 10-6 megahertz

Megahertz = Hertz × 1 × 10-6

Example: 655 Hz × 1 × 10-6 = 0.000655 MHz

Reverse Conversion

To convert megahertz back to hertz:

  • Remember, 1 megahertz equals 1000000 hertz.
  • To convert 0.000655 MHz to Hz, multiply 0.000655 x 1000000, resulting in 655 Hz.

655 Hz is also equal to:

  • 0.655 kilohertz
  • 39300 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

Frequently Asked Questions
