Answer:
SI units, which stands for the International System of Units, are the modern form of the metric system of measurements. SI units are a standardized system used globally for expressing physical quantities. They provide a consistent and coherent framework for measuring various attributes, such as length, mass, time, temperature, electric current, and more.
The SI system is based on seven fundamental base units:
1. Meter (m) for length
2. Kilogram (kg) for mass
3. Second (s) for time
4. Kelvin (K) for temperature
5. Ampere (A) for electric current
6. Candela (cd) for luminous intensity
7. Mole (mol) for amount of substance
These base units are used to derive other units for different physical quantities. The use of SI units simplifies scientific and engineering measurements and ensures consistency and accuracy in communication and calculations across the globe.
