Angular Velocity to RPM Calculator

Need to convert angular velocity to RPM? Our easy Angular Velocity to RPM Calculator helps you make quick and accurate conversions.

Ever wondered how fast something spins? Whether it’s a fan, a wheel, or a motor, knowing its angular velocity and RPM is key. Don’t worry – you don’t need to be a physics expert to understand it. We’re here to make it simple!

In this guide, we’ll show you how to convert angular velocity to RPM. Plus, we’ll introduce our Angular Velocity to RPM Calculator to help you out.

What is Angular Velocity?

Angular velocity tells you how fast something is rotating. It measures the speed of rotation in terms of angles (radians or degrees) per second. Imagine the hands of a clock. As they move, they show angular velocity.

What is RPM?

RPM stands for revolutions per minute. It tells you how many full turns something makes in one minute. A fan that spins at 1,200 RPM completes 1,200 full rotations every 60 seconds. Simple, right?

How to Convert Angular Velocity to RPM

Here’s the good news – the math is pretty easy. To convert angular velocity to RPM, we use this formula:

RPM = ω × (60 / 2π)

Where:

  • ω is the angular velocity in radians per second.
  • π is the constant (around 3.14159).
  • 60 is there to convert seconds into minutes.

This formula will give you the RPM you need. Let’s see how it works with an example.

Example: Let’s Do the Math

Say you have an angular velocity of 10 radians per second. To find the RPM, use the formula:

RPM = (10 × 60) / (2π) ≈ 95.49

So, 10 radians per second equals about 95.49 RPM. Easy, right?

It’s fast, it’s easy, and it saves you time.

Real-World Examples of Angular Velocity to RPM

Let’s take a look at a few examples to make things even clearer. Here’s a simple chart showing different angular velocities and their corresponding RPM:

UnitRPM FormulaResult (RPM)
10 rad/s10 × 60 / (2π)95.49
20 rad/s20 × 60 / (2π)190.98
5 deg/s5 × (π / 180) × 60 / (2π)4.77
50 deg/s50 × (π / 180) × 60 / (2π)47.73

Now you can visualize how different angular velocities translate into RPM. It’s all about understanding the numbers and the math behind them.

What About Angular Velocity of 1 RPM or 200 RPM?

What if you already know the RPM? You can reverse the process. Here’s how you would do it for 1 RPM and 200 RPM.

1 RPM:

Angular Velocity = (2π × 1) / 60 = 0.1047 radians per second

200 RPM:

Angular Velocity = (2π × 200) / 60 = 20.9439 radians per second

Now you know how to go both ways!

How to Find Angular Velocity from RPM and Radius

You can also find angular velocity if you know the RPM and radius. Here’s how to do it:

Angular Velocity = v / r

Where:

  • v is the linear velocity (how fast the edge of the object moves).
  • r is the radius (distance from the center of the rotation).

To calculate v (linear velocity), use this formula:

v = 2πr × RPM × (1 / 60)

This gives you the linear speed, and from there, you can find the angular velocity.

Final Verdict
