How to Convert RPM to Kilohertz
To convert rpm to kilohertz, multiply the frequency by the following conversion ratio: 0.000016667 kilohertz/revolutions per minute.
Since one revolutions per minute is equal to 0.000016667 kilohertz, you can use this simple formula to convert:
The frequency in kilohertz is equal to the frequency in rpm multiplied by 0.000016667.
For example, here's how to convert 5 rpm to kilohertz using the formula above.
How Many Kilohertz Are in a Revolutions per Minute?
There are 0.000016667 kilohertz in a revolutions per minute, which is why we use this value in the formula above.
Our revolutions per minute to kilohertz calculator automatically converts your frequency measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
RPM and kilohertz are both units used to measure frequency. Keep reading to learn more about each unit.
What Is a Revolutions per Minute?
A revolutions per minute is a unit of frequency equal to 1/60 of a hertz (0.0166667 Hz). 1 RPM = 1/60 Hz. [1]
The revolutions per minute is classified as a standard unit of frequency. RPM can be abbreviated as RPM; for example, 1 revolutions per minute can be written as 1 RPM.
When working with rpm (RPM) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, rpm (RPM) are widely used across standard frequency applications within international standard 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 rpm (RPM) and kilohertz (kHz), keep full floating-point precision (1 RPM = 0.000016667 kHz; 1 kHz = 60,000 RPM) during intermediate calculations and round only the final kilohertz figure to match your instrument tolerance.
