Most retailers have sizing charts you can refer to, but you can also find plenty of conversation charts online. Use a ring-sizing chart to convert the measurement.Write down that exact measurement (the more rounding you do, the less accurate the measurement, so try to be precise). Measure the distance from the edge to the line you drew. Unwrap the strip or string and lay it flat next to a ruler.Hold both ends in place and draw a line on the string or paper to mark the point where the ends meet or begin to overlap.
Hold the edge against your finger, and wrap the measuring tool around tightly until it reaches around completely and is perfectly aligned.
