Rad s to RPM Converter: A Comprehensive Guide

Introduction

In the world of motion analysis and engineering, converting between angular velocity units is essential. Two commonly used units are radians per second (rad/s) and revolutions per minute (RPM). Whether you're a physicist, engineer, or hobbyist, this article will provide you with a thorough understanding of rad/s to RPM conversion and its practical applications.

Definition of Rad/s and RPM

Radian per second (rad/s): A unit of angular velocity that represents the rate of change in angular displacement, measured in radians, per second.

Revolution per minute (RPM): A unit of angular velocity that represents the number of complete rotations made around an axis per minute.

Conversion Formula

Converting between rad/s and RPM is straightforward using the following formula:

RPM = (rad/s) * (60 / 2π)

or

Rad/s = (RPM) * (2π / 60)
