How to Convert Kilohertz to Hertz
To convert kilohertz to hertz, multiply the frequency by the following conversion ratio: 1,000 hertz/kilohertz.
Since one kilohertz is equal to 1,000 hertz, you can use this simple formula to convert:
The frequency in hertz is equal to the frequency in kilohertz multiplied by 1,000.
For example, here's how to convert 20 kilohertz to hertz using the formula above.
How Many Hertz Are in a Kilohertz?
There are 1,000 hertz in a kilohertz, which is why we use this value in the formula above.
Our kilohertz to hertz calculator automatically converts your frequency measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Kilohertz and hertz are both units used to measure frequency. Keep reading to learn more about each unit.
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. [1]
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.
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 kilohertz (kHz) and hertz (Hz), keep full floating-point precision (1 kHz = 1,000 Hz; 1 Hz = 0.001 kHz) during intermediate calculations and round only the final hertz figure to match your instrument tolerance.
