Answer 2

The SI system was developed to standardize the units of measurement across all countries so as to facilitate an easier understanding of scientific terms and everyday items.  

• SI stands for Système international. It was first used in France during the 1800s and later adopted by the world in 1960.
• Prior to this, different countries had different groupings of units. Thus, there was a need to unify the units of measurement to facilitate trade and scientific growth.
• Moreover, the SI system is based on multiples of 10 which makes calculations faster and less cumbersome.
• The SI is not fixed but keeps on changing with international agreement as measurement technology advances.
• Thus, a need for a dynamic system that is easy to use and uniform across all regions is what led to the development of the SI system.
