The Distance Between 3 Points Calculator computes the pairwise distances between three points in 3D space. It calculates the straight-line distance (Euclidean distance) between each pair of points (AB, AC, and BC).
The calculator uses the 3D distance formula:
Where:
Explanation: The formula calculates the straight-line distance between two points in 3D space by applying the Pythagorean theorem in three dimensions.
Details: Calculating distances between points is fundamental in geometry, physics, engineering, computer graphics, and many scientific applications. It helps in spatial analysis, object placement, and motion planning.
Tips: Enter the coordinates for all three points (x, y, z for each) and select the units of measurement. The calculator will compute all three pairwise distances (AB, AC, and BC).
Q1: Can this calculator be used for 2D points?
A: Yes, simply set the z-coordinate to 0 for all points to work in 2D space.
Q2: What units should I use for the coordinates?
A: The units can be anything (meters, feet, etc.) as long as all coordinates use the same units. The distance results will be in the same units.
Q3: How accurate are the results?
A: The calculator provides results rounded to 2 decimal places. The underlying calculations use double-precision floating-point arithmetic.
Q4: Can I calculate distances between more than 3 points?
A: This calculator is specifically designed for 3 points. For more points, you would need to calculate each pairwise distance separately.
Q5: What's the maximum distance this calculator can handle?
A: There's no practical limit to the distances it can calculate, but extremely large values might lead to floating-point precision issues.
