If you are measuring the diameter of the ring (which one can assume given the size) then it is about a 10 1/4 ring size.
A 20.2 mm is a 10.5 in the US while a 19.8 is a 10. The sizes are different by country. Refer to the ring size chart in the links below if you need the sizes for different countries.
52.8 mm
3 mm.
16.51 mm inside diameter
8.73 mm

The answer will depend on the units. 20 mm x 8 mm is quite a different size from 20 miles x 8 miles.
3.5 inches is 88.9 millimeters.
i believe you mean US sizes Diam = 20.7 mm Circum = 64.1 mm
A size of 20 mm refers to a measurement of 20 millimeters, which is equivalent to 2 centimeters or approximately 0.79 inches. This size is often used in contexts such as jewelry, watch components, or various mechanical and electronic parts. To visualize it, 20 mm is roughly the width of a large button or the diameter of a standard coin, like a quarter.
