In Italy, the basic unit of measurement is the metre. The International System of Units (SI), the standard metric system in use in the European Union, defines the seven fundamental units used (metre, kilogramme, second, ampere, kelvin, mole, candela)
Italian sizes are in centimetres, unlike US sizes, for example, which are in inches. Women's clothing sizes generally range from about 38 to 56, men's sizes from about 42 to 60. Adult shoe sizes generally go from about 35 to 46.
Sizes and measures can be converted by visiting one of the various internet sites that offer conversion tables.
