Question

what was the need for system international?​

Answer 1

Answer:

The International System of Units (SI), commonly known as the metric system, is the international standard for measurement. The International Treaty of the Meter was signed in Paris on May 20, 1875 by seventeen countries, including the United States and is now celebrated around the globe as World Metrology Day .

1. SI is not based on the arbitrary construct of the human body; rather, on precise and definite standards
2. SI uses base 10, just like our number system, so it is much easier to learn, remember and convert between units.
3. The prefixes used in SI are from Latin and Greek, and they refer to the numbers that the terms represent. (For example, "kilo" as in "kilogram" means 1 000 and "milli" means 1/1000). You can now easily calculate the number of millimeters in a kilometer
4. SI is used in most places around the world, so our use of it allows scientists from disparate regions to use a single standard in communicating scientific data without vocabulary confusion
