Calculator accuracy
The calculators on Circumify use JavaScript\'s built-in
Math.PI, which is accurate to about 15 significant decimal
digits. Displayed results are then rounded to the precision you
select (2, 4, or 6 decimal places).
While we take care to ensure the formulas and code are correct, the calculators are provided for educational and informational purposes only. We make no warranty as to their fitness for any specific application.
Not professional advice
Nothing on the site constitutes engineering, architectural, financial, medical, legal, or any other professional advice. For decisions that depend on precise measurement, consult a qualified professional and verify any calculator output independently. Circumify accepts no liability for losses arising from reliance on the site\'s output.
