Hertz to RPM Converter

Convert hertz to revolutions per minute and RPM to hertz instantly. Bidirectional frequency converter with formula and common values.

Hz

Revolutions per Minute

3,000

RPM

50 Hz = 3,000 RPM

RPM = Hz × 60

Hertz to Revolutions per Minute: 1 Hz equals 60 RPM. To convert hertz to revolutions per minute, multiply by 60 (RPM = Hz × 60). For example, 10 Hz = 600 RPM.

How to Convert Hertz to Revolutions per Minute

To convert from hertz to revolutions per minute, multiply the value by 60. The conversion is linear, meaning doubling the input doubles the output.

Conversion Formula

  • Hertz to Revolutions per Minute: RPM = Hz × 60
  • Revolutions per Minute to Hertz: Hz = RPM ÷ 60

Understanding the Units

What is a Hertz?

The hertz is the SI derived unit of frequency, equal to one cycle per second (1 Hz = 1/s).

Named after Heinrich Hertz (1857–1894), German physicist who experimentally demonstrated electromagnetic waves.

Common contexts: audio, radio, computing clock speeds.

What is a Revolutions per Minute?

One revolution per minute (RPM) equals exactly 1/60 hertz — one full rotation per minute.

Common contexts: engines, motors, turntables.

FAQ

How many RPM are in one hertz?

One hertz equals exactly 60 RPM. Since hertz measures cycles per second and RPM measures revolutions per minute, you multiply by 60 (seconds in a minute).

How do I convert hertz to RPM?

Multiply the frequency in hertz by 60. For example, 25 Hz × 60 = 1,500 RPM.

Where is the Hz to RPM conversion used?

This conversion is common in mechanical engineering for motors, turbines, and rotating machinery. Electric motor speeds driven by variable frequency drives are often specified in Hz but displayed in RPM.

What RPM does a 50 Hz motor run at?

A 2-pole motor on a 50 Hz supply has a synchronous speed of 3,000 RPM (50 × 60). Actual speed is slightly lower due to slip, typically around 2,850-2,950 RPM.

How many revolutions per minute are in 1 hertz?

1 Hz equals 60 RPM.

How do you convert hertz to revolutions per minute?

Multiply the hertz value by 60. Formula: RPM = Hz × 60.

How many revolutions per minute are in 5 hertz?

5 Hz = 300 RPM.

How do you convert revolutions per minute back to hertz?

Use the inverse formula: Hz = RPM ÷ 60. For example, 1 RPM = 0.016667 Hz.

What is the difference between Hertz and Revolutions per Minute?

The hertz is the SI derived unit of frequency, equal to one cycle per second (1 Hz = 1/s). One revolution per minute (RPM) equals exactly 1/60 hertz — one full rotation per minute.
