Question

why is the SI unit needed?

Answer 1

The SI system, also called the metric system, is used around the world. There are seven basic units in the SI system: the meter (m), the kilogram (kg), the second (s), the kelvin (K), the ampere (A), the mole (mol), and the candela (cd).

Answer 2

The International System of units is very important because it helps the whole world understand the measurements in only one set of units and not to transform every single one of them to the one you use to see its worth against the thing you’re comparing. It also helps us not to memorize a lot of units and it’s equals in amount to others. Another thing that is useful is that now, the future of humanity won’t have to complicate to learn all this stuff about lots of measurement units and its equals and all of that. This will also help everybody to understand what people is talking about when they’re talking about measurements because there is for example a British architect talking with an American architect. The American mentions something about this meters and centimeters and kilograms and liters, the British will think: What is this guy talking about? And it would be the other way round but instead of those measurements it would be feet and miles and inches and pints and pounds. And now, I have told all this stuff about why this is important for people to have one same unit system, but now I’m going to talk to you about the measurements. When the humanity was starting to grow in intelligence and all that stuff, people needed a measurement unit. Most civilizations created its own, but with the time this disappeared. Then came the measurement from the medieval times that was created by the British. This is one of the bery few measurements that is still kept. Now, there were a few problems with all those measurements. They were not always exact(no offense to the British, I like what they do). Now, with these new System of Units it is more exact than ever before, and that’s why the International System of Units is very Important
