Cross Product Calculator

Calculate the cross product of two 3D vectors and view the perpendicular result vector and its magnitude.

Enter two 3D vectors A = (x, y, z) and B = (x, y, z). The result is A × B.

How it works

For vectors A = (a₁, a₂, a₃) and B = (b₁, b₂, b₃), the cross product is:
A × B = (a₂b₃ − a₃b₂, a₃b₁ − a₁b₃, a₁b₂ − a₂b₁)

Examples

  • (1, 0, 0) × (0, 1, 0) = (0, 0, 1)
  • (1, 2, 3) × (4, 5, 6) = (-3, 6, -3)

FAQ

  • What is a cross product?

    The cross product combines two 3D vectors and returns a new 3D vector perpendicular to both input vectors.

  • Does cross product work in any dimension?

    This calculator is for 3D vectors. The standard vector cross product is defined in 3D.

  • What does a zero cross product mean?

    A zero result means the vectors are parallel, anti-parallel, or one of them is the zero vector.

  • Are calculations stored?

    No. Everything runs locally in your browser.
