About this conversion

A US 5 ring converts to a France 49. Inner circumference ≈ 49.3 mm · diameter ≈ 15.7 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.
