O-Ring Cut Length

Calculate how long to cut your o-ring cord:

Calculated O-ring Cord Cut Length
( ( OD + ID ) / 2 ) x Pi = length
Pi=3.14159
Use either millimeters or inches for input
Result should be interpreted in your input unit - mm or inch. Hit the calculate button or tab key.

Inside Diameter (ID) = Outside Diameter (OD) - twice the cross section (C/S)
ID = OD - (2 x C/S)

O-Ring Outside Diameter	O-Ring Inside Diameter	O-Ring cord Unit Length

Please note that spliced/vulcanized o-rings should only be used for static applications.
