Answer» TheInternational System of Units(SI, abbreviated from theFrench is the modern form of themetric system, and is the most widely usedsystem of measurement. It comprises acoherentsystem ofunits of measurementbuilt on sevenbase unitsthat areampere,kelvin,second,metre,kilogram,candela,mole The SI system is important in science and technology because it provides a consistent and coherent system of units for all physical quantities, derived from a few base units.This means that you do not need to use any sort of conversion factor between different units;. This becomes especially important in fields like thermodynamics where you often need fairly complex compound units like watts per kelvin per square metre. |
