hertz to rpm | Exact Decimal + Formula

1 Hertz = 60 RPM (Revolutions/min)

One hertz equals exactly 60 rpm — a fixed ratio you can memorize. Real-world use: audio frequencies, processor clock rates, and AC power mains (50/60 hz). This page expresses those values in rpm, which is used for car engines, hard drives, washing machines, and any rotating machinery. Enter any value above — the result updates instantly, and a 1–1000 reference table follows below.

About Hertz and RPM (Revolutions/min)

Hertz (Hz)

The hertz measures cycles per second.

Where it's used: Audio frequencies, processor clock rates, and AC power mains (50/60 Hz).

RPM (Revolutions/min) (rpm)

RPM (revolutions per minute) measures rotational speed; one RPM is 1/60 hertz.

Where it's used: Car engines, hard drives, washing machines, and any rotating machinery.

Hz to rpm Formula and Examples

Direct Formula rpm = Hz × 60

Inverse Formula Hz = rpm × 0.016667

Mental Math Shortcut

Multiply the value by roughly 60 to calculate the equivalent amount in your head.

Common Hertz to RPM (Revolutions/min) Calculations

5 Hz = 300 rpm
10 Hz = 600 rpm
50 Hz = 3000 rpm
100 Hz = 6000 rpm
500 Hz = 30000 rpm

Precision & Practical Use

For example, 10 Hz = 600 rpm — roughly multiple unit increments.

Results are computed to up to 9 decimal places. Round to the precision of your measuring instrument — for most frequency applications, 2–3 significant figures are plenty.

How to Convert Hertz to RPM (Revolutions/min)

How many rpm (revolutions/min)s are in one hertz?

One Hertz (Hz) equals 60 RPM (Revolutions/min) (rpm). To convert hertzes to rpm (revolutions/min)s, multiply the hertz value by 60.

How do I convert Hertz to RPM (Revolutions/min)?

Multiply your hertz value by 60 to get the result in RPM (Revolutions/min): rpm = Hz × 60. For example, 5 Hz = 300 rpm.

What is the formula for converting Hz to rpm?

The conversion formula is rpm = Hz × 60. Use the calculator above for any value, and see the reference table below for common inputs from 0.001 to 1000.
