Angular Acceleration Converter

Convert angular acceleration values among common SI, metric and customary units. Angular acceleration is the rate of change of angular velocity. Radians are dimensionless in SI, but writing rad/s² keeps the rotational meaning clear.

How to use this converter

1. Enter the angular acceleration value.
2. Select its current unit and the unit you want.
3. Select Convert. The page shows the converted value, the SI-base value and the direct multiplication factor.

Conversion formula

Converted value = entered value × source-to-SI factor ÷ target-to-SI factor.

Every option is represented by its factor to radian per second squared (rad/s²). This one-base method keeps reciprocal conversions consistent. Calculations run in your browser, and old results are hidden when an input changes or validation fails.

Worked example

Convert 1 rad/s² to rev/s². Multiply by 0.1591549431; the result is 0.1591549431 rev/s². The same input equals 1 rad/s² in the SI-base unit.

Accuracy and limitations

This is a unit conversion, not a rotational-motion model. It does not calculate torque, moment of inertia or time-varying acceleration.

The calculator retains more digits internally than it displays. Round the final value to the precision supported by your measurement. Very large and very small answers may use scientific notation.

Frequently asked questions

Why does rev/min² use 3,600 in its factor?

A minute is 60 seconds, and the time term is squared, so the factor contains 60².

Can I reverse the conversion?

Yes. Swap the From and To selections. Because both units use the same SI base, the reverse factor is the reciprocal of the forward factor.

Why was my entry rejected?

Use digits with an optional decimal point or scientific notation. Blank values, commas, fractions, words and non-finite entries are rejected. Negative values are allowed when they express direction or polarity.

Review notes and sources

Reviewed October 4, 2026. The conversion factors, default example, zero or signed boundary behavior, invalid-input handling and recovery after an error were checked. Factors follow SI definitions and published conversion guidance from the NIST Guide to the SI and the BIPM SI Brochure. Explanations and examples are original.
