mhz to hertz | Exact Decimal + Formula

1 Megahertz = 1000000 Hertz

One megahertz equals exactly a million hertz. Real-world use: fm radio, computer bus speeds, and older processor clocks. This page expresses those values in hertz, which is used for audio frequencies, processor clock rates, and AC power mains (50/60 hz). Enter any value above — the result updates instantly, and a 1–1000 reference table follows below.

About Megahertz and Hertz

Megahertz (MHz)

A megahertz is 1,000,000 hertz.

Where it's used: FM radio, computer bus speeds, and older processor clocks.

Hertz (Hz)

The hertz measures cycles per second.

Where it's used: Audio frequencies, processor clock rates, and AC power mains (50/60 Hz).

MHz to Hz Formula and Examples

Direct Formula Hz = MHz × 1000000

Inverse Formula MHz = Hz × 0.000001

Mental Math Shortcut

Multiply the value by roughly 1000000 to calculate the equivalent amount in your head.

Common Megahertz to Hertz Calculations

5 MHz = 5000000 Hz
10 MHz = 10000000 Hz
50 MHz = 50000000 Hz
100 MHz = 100000000 Hz
500 MHz = 500000000 Hz

Precision & Practical Use

For example, 10 MHz = 10000000 Hz — roughly multiple unit increments.

Results are computed to up to 9 decimal places. Round to the precision of your measuring instrument — for most frequency applications, 2–3 significant figures are plenty.

How to Convert Megahertz to Hertz

How many hertzes are in one megahertz?

One Megahertz (MHz) equals 1000000 Hertz (Hz). To convert megahertzes to hertzes, multiply the megahertz value by 1000000.

How do I convert Megahertz to Hertz?

Multiply your megahertz value by 1000000 to get the result in Hertz: Hz = MHz × 1000000. For example, 5 MHz = 5000000 Hz.

What is the formula for converting MHz to Hz?

The conversion formula is Hz = MHz × 1000000. Use the calculator above for any value, and see the reference table below for common inputs from 0.001 to 1000.
