What is the difference between the beauty number and the port number in the ring number?

American standards are also based on the algorithm of increasing perimeter. First, the perimeter of No.4 is equal to 1.85 inches, that of No.5 is equal to 1.95 inches, and that of No.6 is equal to 2.05 inches.

The port number is calculated by subtracting 40 from the perimeter. For example, the circumference of 44mm is No.4, and the circumference of 62mm is No.22. ..
