How to Convert Megahertz to Kilohertz
To convert megahertz to kilohertz, multiply the frequency by the following conversion ratio: 1,000 kilohertz/megahertz.
Since one megahertz is equal to 1,000 kilohertz, you can use this simple formula to convert:
The frequency in kilohertz is equal to the frequency in megahertz multiplied by 1,000.
For example, here's how to convert 5 megahertz to kilohertz using the formula above.
How Many Kilohertz Are in a Megahertz?
There are 1,000 kilohertz in a megahertz, which is why we use this value in the formula above.
Our megahertz to kilohertz calculator automatically converts your frequency measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Megahertz and kilohertz 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 Kilohertz?
A kilohertz is a unit of frequency equal to 1,000 hertz (Hz), the base unit for frequency. Equal to 1,000 Hz. [2]
The kilohertz is classified as a metric and SI-compatible unit of frequency. Kilohertz can be abbreviated as kHz; for example, 1 kilohertz can be written as 1 kHz.
In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilohertz (kHz) a convenient decimal multiple of the hertz (Hz).
In practice, kilohertz (kHz) 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 megahertz (MHz) and kilohertz (kHz), keep full floating-point precision (1 MHz = 1,000 kHz; 1 kHz = 0.001 MHz) during intermediate calculations and round only the final kilohertz figure to match your instrument tolerance.
