# Distance between 3D Points

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

d = ((x2 - x1)2 + (y2 - y1)2 + (z2 - z1)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 P1(1,1,0) and point P2(2,1,2)  can be calculated as

d = ((2 - 1)2 + (1 - 1)2 + (2 - 0)2)1/2

= 2.24
