Use our free Vector Calculator to quickly determine the magnitude or length of a 2D or 3D vector. Simply input the coordinates of two points (P1 and P2) to find the distance between them, which represents the vector's magnitude. Perfect for physics, engineering, and geometry problems.
Formula:
The magnitude (or length) of a vector v from point P1(x1, y1, z1) to P2(x2, y2, z2) is calculated as:
|v| = √((x2 - x1)2 + (y2 - y1)2 + (z2 - z1)2)
For 2D vectors, simply enter '0' for the z-components.
