What's the difference between 2D and 3D distance?

2D distance uses only x and y coordinates (like on a map), while 3D distance includes a z-coordinate for height or depth. 3D is used for real-world spatial calculations, while 2D is common for maps and flat surfaces.

Is this the shortest distance between two points?

Yes, this calculates the Euclidean distance, which is the shortest straight-line distance between two points. In real-world navigation, actual travel distance may be longer due to roads, obstacles, or terrain.

Can I use this for geographic coordinates?

For small distances, yes, but for large geographic distances, you should use the haversine formula which accounts for Earth's curvature. This calculator assumes a flat coordinate system.

What units does the result use?

The result uses the same units as your input coordinates. If you enter coordinates in meters, the distance will be in meters. If in miles, the distance will be in miles.
