About this conversion

A US 11 ring converts to a France 65. Inner circumference ≈ 64.6 mm · diameter ≈ 20.6 mm. Ring sizes all describe one physical measurement — the inner circumference of the band — that each country labels differently.

To check at home, measure the inside diameter of a ring that already fits and compare it to the millimetre figure above.
