Important Use Notice

Informational calculator only. Verify important outputs independently before legal, tax, medical, engineering, safety-critical, contractual, employment, or compliance use.

Estimate

Enter job values, review the estimate, then use the decision hints before ordering or quoting.

Estimate Results

Enter values to see the result.

Check

Mixing units or scales across number of sides before calculating exterior angle.
Rounding too early when the exterior angle still feeds another step.

Example

6 gives Exterior Angle 60.

Formula

exterior angle = 360 / n

A full turn around any regular polygon is 360 degrees, so divide by the number of sides.

Regular polygons have equal exterior angles.
