How the 2D Distance Calculator works

Find the straight-line distance between two points in a Cartesian plane.

Formula

√((x2-x1) × (x2-x1)+(y2-y1) × (y2-y1))

How to use this calculator

  1. Enter every measurement using one consistent length or angle unit.
  2. Select Calculate to evaluate the formula.
  3. Review the substituted values in the calculation explanation.

Interpretation and limitations

Coordinates must use the same scale and unit. The result is always non-negative. Decimal answers are rounded for display; retain additional precision for subsequent calculations.
