 --------------------------------
 
 Linear acceleration describes how fast the speed changes. This is expressed as
-the change of the millimeters per second, during one second (deg/s/s).
+the change of the millimeters per second, during one second (mm/s/s).
 This is also commonly written as  :math:`mm/s^2`.
 
 For example, you can adjust the acceleration setting of a
 :class:`DriveBase <.robotics.DriveBase>` to change how
 smoothly or how quickly it reaches the constant speed set point.
