How Turkey ring sizes relate to US sizes

Turkey size is calculated from a ring's inner circumference in millimeters, minus 40. US/Canada uses a separate numeric scale based on inner diameter, so the numbers cannot be converted by simply adding or subtracting a fixed amount. The chart and calculator match both systems through the same physical ring measurement.
