This standardized system has come to be called the \ International System of Units \, abbreviated SI. In order to better communicate measurements, we needed a standardized system of units, which every scientist and measurer could use to share their findings. For example, length can be measured by the foot, meter, fathom, chain, parsec, league, and so on. There are now dozens of units to describe physical quantities.
