The Cross Product Matrix Calculator on our website is a powerful mathematical tool designed to compute the cross product of two three-dimensional vectors quickly and accurately. Whether you’re a student studying linear algebra, physics, engineering, or computer graphics, this calculator helps you find the resulting vector using the matrix (determinant) method in seconds.
The cross product is a fundamental vector operation used in physics, engineering mechanics, robotics, computer graphics, and more. Manually calculating it can be time-consuming and prone to errors. Our tool eliminates confusion and delivers precise results instantly.
What Is a Cross Product?
The cross product (also known as the vector product) is a binary operation on two vectors in three-dimensional space. It produces another vector that is perpendicular to both original vectors.
If:
Vector A = (A₁, A₂, A₃)
Vector B = (B₁, B₂, B₃)
Then the cross product A × B is calculated using the determinant of a 3×3 matrix:
| i j k |
| A₁ A₂ A₃ |
| B₁ B₂ B₃ |
The result is:
A × B =
( A₂B₃ − A₃B₂ ,
A₃B₁ − A₁B₃ ,
A₁B₂ − A₂B₁ )
This resulting vector is perpendicular to both A and B.

Practical Example
Let’s calculate:
Vector A = (2, 3, 4)
Vector B = (5, 6, 7)
Using the formula:
C₁ = (3×7 − 4×6) = (21 − 24) = -3
C₂ = (4×5 − 2×7) = (20 − 14) = 6
C₃ = (2×6 − 3×5) = (12 − 15) = -3
So:
A × B = (-3, 6, -3)
Our Cross Product Matrix Calculator performs this instantly and without mistakes.

Properties of Cross Product
Understanding these properties helps verify results:
- A × B = −(B × A)
- A × A = 0
- Result is perpendicular to both vectors
- Magnitude = |A||B| sin(θ)
Where θ is the angle between the vectors.
Magnitude of the Cross Product
The magnitude represents the area of the parallelogram formed by the two vectors.
|A × B| = |A||B| sin(θ)
This is extremely useful in geometry and physics.
