How to Convert Hertz to Megahertz

To convert hertz to megahertz, multiply the frequency by the following conversion ratio: 0.000001 megahertz/hertz.

Since one hertz is equal to 0.000001 megahertz, you can use this simple formula to convert:

megahertz = hertz × 0.000001

The frequency in megahertz is equal to the frequency in hertz multiplied by 0.000001.

For example, here's how to convert 1000000 hertz to megahertz using the formula above.

megahertz = (1000000 Hz × 0.000001) = 1 MHz

How Many Megahertz Are in a Hertz?

There are 0.000001 megahertz in a hertz, which is why we use this value in the formula above.

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

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

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

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. [1]

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.

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. [2]

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.

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