CALCULATOR
Circumference to Diameter Calculator
Find diameter from measured circumference. Example: Circumference: 2 m gives 0.636619772368 m. A complete circle boundary. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation.
A complete circle boundary. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation. Derivation: Invert C = πd.
Accepted inputs: Circumference: 0.001 to 1,000 m.
How the calculation works
diameter = circumference/π
Worked example
With circumference 2 m, diameter from measured circumference is 0.6366197724 m.
Assumptions and limits
