# Distance between Two Points in 3D

## Distance between two points in a three dimension coordinate system - online calculator

The distance between two points in a three dimensional - 3D - coordinate system can be calculated as

*d = ((x _{2} - x_{1})^{2} + (y_{2} - y_{1})^{2} + (z_{2} - z_{1})^{2})^{1/2} (1) *

*where *

*d = distance (m, inches ...)*

*x, y, z = coordinates*

### Example - the Distance between two points in a three dimensional space

The distance between point *P _{1}(1,1,1)* and point

*P*can be calculated as

_{2}(2,2,2)*d = ((2 _{} - 1_{})^{2} + (1 - 1_{})^{2} + (2_{} - 0_{})^{2})^{1/2} *

* = 2.24*
