What Is This Tool?
This converter transforms values from revolution per minute (r/min), a unit measuring the number of complete turns per minute, into radian per second (rad/s), the SI unit for angular velocity representing angular displacement per second. It is widely used for precise calculations in engineering, physics, and control systems.

Tips & Best Practices
-
Ensure the angular velocity is steady when using this conversion for precise results.
-
Maintain sufficient decimal accuracy to reduce rounding errors.
-
Use this conversion mainly for uniform rotational motion where revolutions per time relate directly to angular displacement.
-
Apply the converted radian per second values for further physics or control system modeling.
Limitations
-
Assumes constant angular velocity, not accounting for changing rotational speeds.
-
Precision can be affected by rounding decimal values.
-
Not suitable for non-uniform or irregular rotational motion where revolutions do not correspond directly to angular displacement.
Frequently Asked Questions
-
What does revolution per minute (r/min) measure?
-
Revolution per minute (r/min) counts how many full turns an object completes around an axis each minute.
-
Why convert r/min to radian per second (rad/s)?
-
Converting to rad/s allows expressing angular velocity in the SI unit system, which is essential for precise engineering and physics calculations.
-
Can this converter be used for non-constant rotational speeds?
-
No, it assumes constant angular velocity and does not account for transient or varying rotational speeds.
