Explanation:
The SI system is the system of measurement that is the most widely used around the world. It is actually the modern day version of the metric system. The majority of the countries in the world use this measuring system, but there are few that don't, such as the United States, Liberia, and Myanmar (Burma). Canada and the United Kingdom are kind off in an in between situation, as they have this system as official, but the population still very often uses other measurements that are tradition, often leading to confusion.
This measuring system has seven base unites:
second (s) - measures time
meter (m) - measures length
kilogram (kg) - measures mass
ampere (A) - measures electric current
kelvin (K) - measures temperature
mole (mol) - measures amount of substance
candela (cd) - measures luminous intensity
