Distance between two points

How to use this calculator

1. Enter first x coordinate. Use the unit shown beside the field.
2. Enter first y coordinate. Use the unit shown beside the field.
3. Enter second x coordinate. Use the unit shown beside the field.
4. Enter second y coordinate. Use the unit shown beside the field.
5. Select Calculate and review the result. Select Reset to restore the example inputs.

How the calculation works

sqrt((Second x coordinate-First x coordinate)**2+(Second y coordinate-First y coordinate)**2)

Worked example

First x coordinate = 0; First y coordinate = 0; Second x coordinate = 3; Second y coordinate = 4. Result: 5 coordinate units.
