RPM to Acceleration Calculator


RPM (Revolutions Per Minute) measures how many rotations an object completes in a minute. It’s often used to describe the speed of rotating things like engines, wheels, or motors.

Acceleration refers to how quickly the velocity of an object changes. When an object accelerates, it’s gaining speed or changing direction. This change in speed over time is a crucial aspect of understanding how objects move.


The formula for converting RPM (Revolutions Per Minute) to linear acceleration is

Alpha (α) =RPM×2π×R/60

  • Alpha (α) = Linear acceleration (in meters per second squared, m/s²)
  • RPM = Rotations per minute
  • R = Radius of rotation (in meters)
  • 2π = Constant value (approximately 6.28318)
  • 60 = Conversion factor (seconds per minute)

Suppose you’re working with a circular saw blade in a woodworking shop. The blade has a radius of 24 meters and is rotating at 500 RPM. Calculate the linear acceleration of a point on the edge of the saw blade.



  • RPM=500
  • R=24

Using the formula for linear acceleration:

Alpha (α)= 500×2π×24 / 60

Simplify the calculation:

Alpha (α)= 75360 / 60

Alpha (α)=40π ≈ 1256m/s²

So, the linear acceleration of a point on the edge of the saw blade is approximately 1256m/s²

How to Use RPM to Acceleration Calculator:

To calculate acceleration from RPM, follow these steps:

  1. Enter the value of RPM (Revolutions Per Minute) into the “RPM” field. 
  2. Input the radius of the rotating object into the “Radius (m)” field.
  3. Click the “Calculate” button to perform the calculation.
  4. The calculator will display the calculated acceleration in meters per second squared (m/s²) below the “Calculate” button.
  5. If you need to calculate another acceleration or you made a mistake, there’s a button called “Reset.” Clicking it will clear the boxes and the result, so you can start fresh.

At The End

The RPM to Acceleration Calculator is a valuable tool that helps us translate rotations into acceleration. By plugging in RPM and radius values, we can quickly determine how fast an object’s speed changes over time. With its user-friendly interface and clear formula, the calculator simplifies converting RPM to acceleration, making it an excellent asset for understanding motion and speed.
