Estimate distance between points using clear inputs and transparent formulas, with results intended for planning and comparison.
How to use this calculator
For distance between points calculator, enter First point x, First point y, First point z, Second point x, the remaining displayed fields using the unit or format beside each field. Select Calculate to apply the formula below, review all returned values together, and use Reset to restore the demonstrated inputs before testing another scenario.
Formula & calculation method
distance = sqrt(pow(x2-x1,2)+pow(y2-y1,2)+pow(z2-z1,2)); squaredDistance = pow(x2-x1,2)+pow(y2-y1,2)+pow(z2-z1,2)Worked example
For a reproducible distance between points calculator example, use First point x: 0; First point y: 0; First point z: 0; Second point x: 3; plus the remaining displayed defaults. The first returned value, distance between points, is calculated with sqrt(pow(x2-x1,2)+pow(y2-y1,2)+pow(z2-z1,2)); the other results describe the same scenario. Change one input at a time and keep its unit consistent when comparing scenarios.
