Vector Magnitude Calculator
Calculate magnitude and normalize vectors to unit length.
Magnitude (Length)
Unit Vector
The unit vector has magnitude 1 and points in the same direction.
Magnitude Formula
|v| = √(v₁² + v₂² + ... + vₙ²)
The magnitude (or length) of a vector is the square root of the sum of squared components.
Unit Vector Formula
û = v / |v|
Divide each component by the magnitude to get a unit vector pointing in the same direction.
