Convert 120 Hertz (Hz) to Revolutions/Second (rps).

120 Hertz equals 120 Revolutions/Second. Multiply 120 by 1.

120 Hertz = 120 Revolutions/Second

Worked example: converting Hertz to Revolutions/Second

Step 1 — start with the formula. rps = Hz × 1
Step 2 — substitute your figure. 120 Hz × 1
Step 3 — read the result. 120 Hz = 120 rps
Step 4 — check it in reverse. Hz = rps × 1 returns 120 Hz, which matches the figure you started with.

How to Convert Hertz to Revolutions/Second

To convert from Hertz (Hz) to Revolutions/Second (rps), multiply the value by 1.

Formula: rps = Hz × 1

Reverse: Hz = rps × 1

Step-by-Step Example

Start with your value in Hertz. For example: 5 Hz
Multiply by the conversion factor: 5 x 1
The result is: 5 rps

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/Second

The revolutions/second (rps) is a unit of frequency. One revolutions/second 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.
