### fineness modulus definition gives information

Fineness A measure of the purity of a precious metal as a unit of 1,000 That is, a fineness measure of 1 means that 01% of a substance is a given precious metal, while a measure of 1,000 means that 100% is the metal Fineness is important to commodities and futures involving precious metals, in which the quality of the underlying metals must be .
