How to Convert Hertz to RPM
To convert hertz to rpm, multiply the frequency by the following conversion ratio: 60 rpm/hertz.
Since one hertz is equal to 60 rpm, you can use this simple formula to convert:
The frequency in rpm is equal to the frequency in hertz multiplied by 60.
For example, here's how to convert 5 hertz to rpm using the formula above.
How Many RPM Are in a Hertz?
There are 60 rpm in a hertz, which is why we use this value in the formula above.
Our hertz to revolutions per minute calculator automatically converts your frequency measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Hertz and rpm 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 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. [2]
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.
When converting frequency between hertz (Hz) and rpm (RPM), keep full floating-point precision (1 Hz = 60 RPM; 1 RPM = 0.0166667 Hz) during intermediate calculations and round only the final revolutions per minute figure to match your instrument tolerance.
