Convert Hertz to Megahertz

Whether you need to express a value in MHz instead of Hz, this guide walks you through the exact steps. Frequency conversions relate to radio waves, processor clock speeds, and audio pitch — from hertz through gigahertz.

To convert, multiply the hertz value by 1.0000e-6. Written as an equation: MHz = Hz × 1.0000e-6.

One hertz equals approximately 0.000001 MHz. This means you can multiply any Hz value by 0.000001 to get the equivalent in MHz.

Worked example: 5 Hz = 0.000005 MHz. Enter your own value in the converter above for instant results.

Common mistake: Always include the correct prefix (kilo-, mega-, giga-) — confusing MHz with GHz leads to errors of a thousandfold.
