At any distance from the axis of rotation, the linear speed of an object is directly proportional to the rotational speed. If the linear speed increases, the rotational speed also increases.

the units for rotational speed are radians / sec or degrees / sec

It is a sensor on the transmission that reads the rotational speed of the input shaft.

It is a sensor on the transmission that reads the rotational speed of the input shaft.

it depends on more then rotational speed.

The Rotational speed and latency time is related as follows:

Latency time = (1/((Rotational Speed in RPM)/60)) * 0.5 * 1000 milli seconds

(linear speed) = (rotational speed) x (radius or distance from the center)

To use consistent measures, use radians/second for rotational speed, meters for the radius, and meters/second for the linear speed. If you know rotational speed in some other unit - for example, rpm (rotations per minute) - convert to radians per second first.
