Distance Calculator

Calculate distance between two points in 2D space, 3D space, or geographic coordinates on Earth using the Haversine formula.

Understanding Distance in Coordinate Systems

In Cartesian coordinate geometry, Euclidean distance between two points is derived from the Pythagorean theorem. In three-dimensional space, an additional z-axis delta is added under the radical.

Frequently Asked Questions

What is the midpoint formula?

The midpoint M of two points (x1, y1) and (x2, y2) is the exact center coordinate given by M = ((x1 + x2) / 2, (y1 + y2) / 2).
