Distance
Our three-dimensional distance calculator is a tool that finds the distance between two points with given coordinates in space. If you want to determine the distance between two points on a plane (two-dimensional distance), use our distance calculator.
The distance formula
To find the distance between two points in a three-dimensional coordinate system, you need to apply the following formula:
D = √[(x₂ - x₁)² + (y₂ - y₁)² +(z₂ - z₁)²]
where:
Dis the distance between two points,(x₁, y₁, z₁)are the coordinates of the first point,(x₂, y₂, z₂)are the coordinates of the second point.
Notice that the value obtained when using this formula is always positive. This is because we consider a scalar value of distance - it does not depend on the numbering of points.
How to calculate the 3d distance
- Choose the coordinates of the first point - for example (1,1,1).
- Choose the coordinates of the second point - for example, (3,6,9).
- Input these values to the formula:
D = √[(x₂ - x₁)² + (y₂ - y₁)² +(z₂ - z₁)²] = √[(3-1)² + (6-1)² +(9-1)²]
- Calculate the result:
D = √[2² + 5² +8²] = √[4 + 25 +64] = √93 = 9.643
