See…A unit vector has magnitude 1, with no units. The unit vector is represented by a letter marked with a hat. a unit vector has a magnitude 1, with no units, means that if you multiply a unit vector by a scalar, the resulting vector has a magnitude equal to the value with- units of the scalar.  Hope u understood :)
