How Indian ring sizes translate to US sizes

Leading Indian jewelers (such as Bluestone, CaratLane, and Jewelove) define Indian ring size numbers as the inner circumference in millimeters minus 40 (Size = Circumference in mm - 40). US sizes use an independent diameter scale. For example, an Indian size 12 corresponds to a 52 mm circumference, which aligns with US size 6. An Indian size 14 corresponds to a 54 mm circumference, aligning with US size 6¾.
