Other quantities, called derived quantities, are defined in terms of the seven base quantities via a system of quantity equations.The SI derived unitsfor these derived quantities are obtained from these equations and the seven SI base units. The SI base unit is the meter and as with the gram, the metric prefixes allow us to express measurements in a number of different sizes from the millimeter (1/1000 of a meter) to the kilometer (1000 meters). This led to a number of the other SI base units being defined indirectly in terms of the mass of the same artefact; the mole, the ampere, and the candela were linked through their definitions to the mass of the International Prototype of the Kilogram, a roughly golfball-sized platinum–iridium cylinder stored in a vault near Paris. He urged the CIPM to accept the proposed changes in the definition of the kilogram, ampere, kelvin, and mole so that they are referenced to the values of the fundamental constants, namely the Planck constant (h), the electron charge (e), the Boltzmann constant (k), and the Avogadro constant (NA). ; The basic unit of mass in the SI system is the kilogram (kg), which is about 10% bigger than two pounds.
