About the 3D Distance Calculator

The 3D distance formula extends the Pythagorean theorem to three dimensions, measuring the straight-line separation between two points in space.

Formula: d = √((x₂−x₁)² + (y₂−y₁)² + (z₂−z₁)²)

This formula is used in 3D graphics, physics simulations, robotics and engineering to measure real-world spatial distances.
