Cross Product Calculator

Cross product of two 3D vectors.

Compute the cross product (vector product) of two 3-dimensional vectors, plus its magnitude — useful for torque, angular momentum, and finding a vector perpendicular to two others.

Formula

(a × b)_x = a_y·b_z − a_z·b_y. (a × b)_y = a_z·b_x − a_x·b_z. (a × b)_z = a_x·b_y − a_y·b_x.
