There are charts on the internet, but an easy way to figure it out is to measure your head with a tape just above your ears, or wherever you wear your hat. If you are on the metric system, divide the measurement in centimeters by 2.54 to convert to inches. Then, divide by pi (use 3.14) to get the radius, which is your U.S. hat size.
57 cm / 2.54 = 22.44 inches
22.44" / 3.14 = 7.15, which is close to 7.125, or 7-1/8
Of course, sizes vary from manufacturer to manufacturer and from hat to hat.
