How to Convert Megahertz to Hertz

To convert megahertz to hertz, multiply the frequency by the following conversion ratio: 1,000,000 hertz/megahertz.

Since one megahertz is equal to 1,000,000 hertz, you can use this simple formula to convert:

hertz = megahertz × 1,000,000

The frequency in hertz is equal to the frequency in megahertz multiplied by 1,000,000.

For example, here's how to convert 100 megahertz to hertz using the formula above.

hertz = (100 MHz × 1,000,000) = 100,000,000 Hz

How Many Hertz Are in a Megahertz?

There are 1,000,000 hertz in a megahertz, which is why we use this value in the formula above.

1 MHz = 1,000,000 Hz|1 Hz = 0.000001 MHz

Our megahertz to hertz calculator automatically converts your frequency measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Megahertz and hertz are both units used to measure frequency. Keep reading to learn more about each unit.

What Is a Megahertz?

A megahertz is a unit of frequency equal to 1,000,000 hertz (Hz), the base unit for frequency. Equal to 1,000,000 Hz. [1]

The megahertz is classified as a metric and SI-compatible unit of frequency. Megahertz can be abbreviated as MHz; for example, 1 megahertz can be written as 1 MHz.

In the metric system, "mega" is the standard SI prefix for millions, or 10⁶. This makes the megahertz (MHz) a convenient decimal multiple of the hertz (Hz).

In practice, megahertz (MHz) are widely used across large-scale industrial, bulk, and macro-level frequency specifications within SI metric workflows, engineering documentation, and technical data sheets.

What Is a Hertz?

SI unit of frequency equal to 1 cycle per second. It serves as a primary reference unit for measuring frequency across scientific and practical applications. [2]

The hertz is classified as an International System of Units (SI) unit of frequency. Hertz can be abbreviated as Hz; for example, 1 hertz can be written as 1 Hz.

As the primary coherent reference unit for frequency in this category, all other frequency units are mathematically anchored to the hertz (Hz).

In practice, hertz (Hz) are widely used across standard frequency applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.

When converting frequency between megahertz (MHz) and hertz (Hz), keep full floating-point precision (1 MHz = 1,000,000 Hz; 1 Hz = 0.000001 MHz) during intermediate calculations and round only the final hertz figure to match your instrument tolerance.
