Use this geometry calculation when the shape, dimensions, coordinate system, and units match the stated ideal Euclidean model.

First point

Required list input.

Second point

Required list input.

Calculate straight-line distance between two equal-length points or vectors. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Euclidean distance

The resulting euclidean distance returned as a number.

• The result assumes exact idealized geometry. Measurement uncertainty, rounded inputs, nonplanarity, self-intersection, thickness, curved coordinate systems, and ambiguous dimension definitions are not automatically represented.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Sketch and label the dimensions, verify unit consistency, and use coordinate or CAD methods for irregular measured shapes.
