Conversions within the American system (such as pounds to ounces, the number of feet in a mile, the number of inches in a foot, etc). • The number is called Avogadro’s number. The mole (symbol: mol) is the unit of measurement for amount of substance in the International System of Units (SI). In order to correctly convert one metric unit to another, you will need to determine which of two prefixes represents a bigger amount and then determine the exponential "distance" between them.
