You got to tell us what kind of unit vector is it.

A unit vector is the same in all measurement systems. It gives a direction and nothing else. The direction of the unit vector is arbitrary, the magnitude is one (no dimensions). In a three dimensional coordinate system, there is a unit vector defining the positive direction of each coordinate.

Phil's hit the nail on the head. If we are talking about the vectors in three-space, the unit of a unit vector would be something like "left", "right", "up" etc.

All unit vectors have a MAGNITUDE of 1, but 1 in what units? Typically you use unit vectors for length, but the units could any number of things: meters, cm's, km's, feet, miles, nanometers, furlongs, whatever.
For SI, the unit would be meters for measuring length and radians for measuring angles.

That's the question of the century.

i think it is concerned with wat kind of vector it is...if it's a force , then "Newton" is the SI unit....if it's a line on paper....then "metres" is the unit..........and so on...
