Angular Acceleration Converter
Angular acceleration is how quickly a rotation speeds up or slows down. The SI unit is the radian per second squared. Motor and servo data sheets often quote revolutions per minute per second instead, which is how fast a drive can change its shaft speed.
6 units supported Base unit radian per second squared (rad/s²)
Multiply the number of radians per second squared by 0.159154943092 to get revolutions per second squared. How this is calculated
About angular acceleration conversion
Angular Acceleration conversion is commonly needed when servo and motor sizing, gearbox design, and vehicle dynamics. Drive data sheets often quote RPM gained per second, which is a revolution-per-minute-per-second figure rather than rad/s².
