About this calculator
The UTIQO Distance Calculator computes the distance between two points in a 2D or 3D Cartesian coordinate system using the Euclidean distance formula. It is designed for students, engineers, and professionals who need quick and accurate distance measurements for geometry, physics, navigation, or design tasks.
How to use
- 1
Select 2D or 3D space using the Space radio buttons.
- 2
Enter the coordinates of the first point (x₁, y₁, and z₁ if 3D) and the second point (x₂, y₂, and z₂ if 3D).
- 3
The distance and midpoint are calculated automatically and displayed below.
Frequently asked questions
What is the distance formula?
For two points (x1, y1) and (x2, y2) in 2D, distance = √((x2−x1)² + (y2−y1)²). In 3D, add (z2−z1)² under the square root.
Can I use negative coordinates?
Yes, the formula works with negative coordinates because differences are squared, always yielding non-negative results.
What if the distance is zero?
A distance of zero means the two points are exactly the same.
