RPM to Hertz Conversion: A Comprehensive Guide

Introduction

In the realm of engineering and physics, rotational speed and frequency play crucial roles. Rotating machinery, such as engines, motors, and fans, operates at specific rotational speeds measured in revolutions per minute (RPM). Conversely, oscillations or vibrations are characterized by their frequency, expressed in hertz (Hz). Understanding the relationship between RPM and Hz is essential for various applications.

Conversion Formula

The conversion between RPM and Hz is straightforward. One hertz represents one cycle per second, while one revolution per minute equates to 1/60 of a cycle per second. Therefore, the conversion formula is:

Frequency (Hz) = RPM / 60

Conversion Examples

• A motor operating at 1,200 RPM has a frequency of 1,200 / 60 = 20 Hz.
• A fan rotating at 500 RPM vibrates at a frequency of 500 / 60 = 8.33 Hz.
