Acceleration - Angular Converter
Convert angular acceleration between radian and revolution based units.
Written by Rahman · Last reviewed
Quick answer
Angular acceleration is the rate of change of angular velocity, in radians per second squared. One revolution per second squared is 2π, or 6.2832 rad/s², and one rpm per second is 0.10472 rad/s². It links to torque through the moment of inertia: torque equals inertia multiplied by angular acceleration.
| Radian per second² (rad/s²) | 1 |
| Radian per minute² (rad/min²) | 3599.999971 |
| Revolution per second² (rev/s²) | 0.1591549431 |
| Revolution per minute per second (rpm/s) | 9.549296587 |
| Revolution per minute² (rev/min²) | 572.9577794 |
About the Acceleration - Angular Converter
Angular acceleration is the rate at which rotational speed changes: how quickly something spins up or slows down. The SI unit is the radian per second squared.
This converter handles radian- and revolution-based units used in the study of rotating machinery and rigid-body dynamics.
Frequently Asked Questions
What is angular acceleration?
⌄
It is the change in angular velocity per unit of time: how fast a rotation speeds up or slows down.
What units measure angular acceleration?
⌄
The SI unit is radians per second squared. Revolutions per minute per second is also common for motors.
How is it different from angular velocity?
⌄
Angular velocity is the rotation rate itself; angular acceleration is how quickly that rate is changing.
