Here's why:
* Universality: SI is the standard system adopted by almost all countries for scientific, technical, and commercial purposes.
* Consistency: It provides a consistent and coherent set of units, making it easier to compare and share scientific data globally.
* Ease of Use: SI uses base units and prefixes, making it easier to express very large or very small quantities.
Some key SI units include:
* Meter (m) for length
* Kilogram (kg) for mass
* Second (s) for time
* Ampere (A) for electric current
* Kelvin (K) for temperature
* Mole (mol) for amount of substance
* Candela (cd) for luminous intensity
While the United States primarily uses the Imperial system, scientists in the US and around the world overwhelmingly use SI for research and communication.
