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 :)

a vector which has magnitude 1

**Unit Vectors**:

A vector of unit magnitude is called a unit vector . It has the same direction as that of the given vector .

A unit vector of is written as and is read as A cap.

= A Or

=

where A = magnitude of .

So, a unit vector in a given direction can also be defined as a vector in that direction divided by the magnitude of the given vector.

It has not unit and dimension. It represents direction only.

Example- are the unit vectors along x axis , y axis and z axis respectively.
