regarding the existing Antilock braking system example model.

In the existing Antilock braking system example model.The wheel speed output is mentioned in unit m/s and vehicle speed output is in rad/sec .But actually when i calculated the wheel speed the output unit is rad/sec only . how did m/sec came ,there is no any block or logic near wheel speed discrete function block that converts rad/sec into m/sec . Then why there is a m/sec .The wheel speed and vehicle speed value goes into slip ratio calculation with mismatched units ,won;t this impact the accuracy of the model.please kindly provide a clarification on this.

Click the block masked as "?" to bring up the help document. It explains the unit of vehicle/wheel speed. There is a Gain block "1/Rr" involved to make the conversion.
