Convert 18 Hertz (Hz) to Revolutions/Minute (rpm).

18 Hertz equals 1,080 Revolutions/Minute. Multiply 18 by 60.

18 Hertz = 1,080 Revolutions/Minute

Worked example: converting Hertz to Revolutions/Minute

Step 1 — start with the formula. rpm = Hz × 60
Step 2 — substitute your figure. 18 Hz × 60
Step 3 — read the result. 18 Hz = 1,080 rpm
Step 4 — check it in reverse. Hz = rpm × 0.0166666667 returns Invalid Hz, which matches the figure you started with.

Standards and context behind Hertz to Revolutions/Minute

Rotational speed: 1 Hz = 60 rpm; motor nameplates use rpm while control systems use hertz.

How to Convert Hertz to Revolutions/Minute

To convert from Hertz (Hz) to Revolutions/Minute (rpm), multiply the value by 60.

Formula: rpm = Hz × 60

Reverse: Hz = rpm × 0.0166666667

Step-by-Step Example

Start with your value in Hertz. For example: 5 Hz
Multiply by the conversion factor: 5 x 60
The result is: 300 rpm

About Hertz

The hertz (Hz) is a unit of frequency. One hertz equals 1 hertz. UnitConvertLab converts it against every other frequency unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: frequency calculations, engineering and science, education.

About Revolutions/Minute

The revolutions/minute (rpm) is a unit of frequency. One revolutions/minute equals 0.01666666667 hertzs. UnitConvertLab converts it against every other frequency unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.
