Units are extremely important in the study of science. Without them, a number is just a number without any meaning. The Système international d’unités (SI system) is a standard that simplifies international scientific communication. This system comprises seven base quantities and 16 prefixes that designate amount. SI Units 339 International System of Units (SI Units) Système International d’Unités, or SI units, are an extension of the meter, kilogram, second, ampere (MKSA) system proposed in 1950. In 1966, the International Federation of Clinical Chemistry (IFCC) recommended the use of selected, or favored, SI units for Chemistry 301. Units .
