Examples of such SI derived units are given in Table 2, where it should be noted that the symbol 1 for quantities of dimension 1 such as mass fraction is generally omitted. The International System of Units is a system of measurement based on the metric system. SI units are easy to use because they are based on the number 10. It is the force required to accelerate a 1-kg mass 1 m/s 2. 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). Furthermore, the seven base units are second, metre, kilogram, ampere, Kelvin, mole, and candela. The Systme international d'units (SI system) is a standard that simplifies international scientific communication. The standard volume is a cubic meter (m3), a cube with an edge length of exactly one meter.
