This ring converter will convert a selected ring size from any of the possible regions to the ring size designation used in different countries. Select a ring size in the drop box selectors and any that are directly convertible will be shown in the corresponding boxes.
If you don't know your ring size, take a piece of string and wrap it around your ring finger where you would wear the ring. Mark the point where the end contacts the length of the string and measure the distance of that string, representing the circumference of your finger. You can enter that amount in the circumference box or divide it manually by PI (3.1417) to get the diameter of your finger.
