What Is This Tool?

This tool converts angular velocity values from revolution per second (r/s), which counts complete rotations per second, to radian per second (rad/s), the SI unit measuring angular displacement rate in radians per second.

How to Use This Tool?

  • Enter the angular velocity value in revolution/second (r/s)
  • Select the input unit as revolution/second and output unit as radian/second
  • Click the convert button to see the equivalent value in radian/second
  • Review the result for use in engineering, physics, or control applications

Key Features

  • Converts velocity angular units from revolution/second to radian/second
  • Uses a precise conversion rate reflecting the relation between revolutions and radians
  • Supports applications in physics, engineering, robotics, and scientific research
  • Browser-based and user-friendly interface for quick conversions

Examples

  • 2 revolution/second equals 12.5663706144 radian/second
  • 0.5 revolution/second equals 3.1415926536 radian/second

Common Use Cases

  • Specifying shaft speeds of electric motors and servos with per-second resolution
  • Describing spin rates of devices like optical discs, flywheels, or turbomachinery during testing
  • Reporting rotation frequencies of scientific instruments such as laboratory rotors or pulsars
  • Applying angular velocity values in robotics, control systems, and vibration analysis

Tips & Best Practices

  • Understand that revolution/second denotes full rotations while radian/second measures continuous angular displacement
  • Use precise values of π for accurate conversions
  • Apply converted values carefully in calculations requiring standard SI angular velocity units
  • Consider the motion uniformity assumption when using this conversion

Limitations

  • Revolution/second counts discrete rotations, while radian/second measures continuous angles
  • The conversion depends on the exact value of π used
  • The conversion assumes uniform circular motion and does not address angular acceleration changes

Frequently Asked Questions

What does one revolution per second represent?
It represents one full rotation around an axis per second, measuring how many complete turns occur each second.

Why convert revolution/second to radian/second?
Converting to radian/second provides an angular velocity in standard SI units, useful for precise physics and engineering calculations.

Can this conversion be applied to non-uniform rotations?
No, this conversion assumes uniform circular motion and does not account for changes in angular acceleration.

Key Terminology

Revolution/second [r/s]
A unit of angular speed representing one complete rotation about an axis per second, indicating the number of full revolutions made each second.
Radian/second [rad/s]
The SI derived unit for angular velocity measuring the rate of angular displacement in radians per second.
