Angular acceleration converter Convert signed angular-acceleration values between SI, degree-based, and revolution-based rate-of-change units used in controls and motion work.

Common presets

Average vs instantaneous

This page converts units only. It does not determine whether your entered value came from an average change over time or an instantaneous measurement.

Sign still matters

Positive and negative values are preserved. Depending on the motion convention you use, the sign may represent speeding up, slowing down, or a reversed axis direction.

Angular acceleration converter: rad/s², deg/s², rpm/s, and related units explained

An angular acceleration converter rewrites how quickly an angular velocity is changing into the unit your engineering, controls, or physics workflow expects. Motion systems may report RPM per second, technical formulas prefer rad/s², and some interfaces use degree-based change rates.

What angular acceleration measures

Angular acceleration describes the rate of change of angular velocity over time. If the spin rate is increasing or decreasing, angular acceleration tells you how quickly that change is happening.

Because the same rotational change can be written in radians, degrees, or revolutions, the acceleration can also be expressed in several equivalent unit families such as rad/s², deg/s², RPM per second, or revolutions per second squared.

α = dω / dt

Defines angular acceleration as change in angular velocity over time.

1 rev/s² = 2π rad/s²

Links revolution-based and SI angular-acceleration units.

1 rpm/s = π / 30 rad/s²

Converts a per-second RPM change into the SI angular-acceleration form.

Average and instantaneous values are different ideas

A measured value may be an average change across a time interval or an instantaneous rate at one moment. The unit conversion is the same either way, but the physical interpretation may not be.

That is why a converter can safely translate the numbers while still leaving the measurement context to the engineer, operator, or analyst.

Why this does not tell you torque by itself

Angular acceleration is closely related to torque, but torque also depends on the system inertia. A converter can translate units, but it cannot infer how much torque caused the change without more information.

That makes this page useful for consistent reporting and comparison, not for replacing a full rotational-dynamics calculation.

Frequently asked questions

What is the difference between angular velocity and angular acceleration?

Angular velocity tells you how fast something is rotating. Angular acceleration tells you how quickly that rotation rate is increasing or decreasing.

 Can angular acceleration be negative?

Yes. Depending on the sign convention and motion context, a negative value can represent slowing down in the positive direction or accelerating in the negative direction.

 Why is rpm/s not the same as rev/s²?

RPM per second changes the rate in revolutions per minute over one second, while rev/s² changes the rate in revolutions per second over one second. The time bases inside the units are different.

 Does this calculator tell me torque?

No. Torque depends on angular acceleration and the system moment of inertia. This page converts units only.
