Read the result
The result is perpendicular to both input vectors. Its magnitude is the area of the parallelogram made by A and B.
Vector algebra
Cross Product Calculator
Calculate A x B, its magnitude, and the area it represents.
Formula
A x B = (AyBz - AzBy, AzBx - AxBz, AxBy - AyBx)
Result
Worked substitution
The cross product is perpendicular to both input vectors.
Where it helps
Use it for area, normals, torque, and any 3D calculation where direction perpendicular to a plane matters.
Common slip
Order matters. A x B and B x A have the same magnitude but opposite directions.
Try it
Swap A and B after calculating. The signs of the cross product should reverse.
