Work out unit vector instantly with clear inputs, formula shown and shareable results.
Normalising divides a vector by its own magnitude, leaving the direction unchanged and the length equal to 1. Multiplying that unit vector by any value gives a vector of exactly that length in the same direction.
Unit vector
û = v / |v|, where |v| = √(x² + y² + z²)
The magnitude is 13, so the unit vector is (3/13, 4/13, 12/13) ≈ (0.2307692, 0.3076923, 0.9230769).
It has no direction and dividing by its zero length is undefined.
