## What are the 3 system of units?

There are as many units as there are independent quantities. We consider length, mass, and time three quantities which are independent of each other. Hence they have three separate units for their measurements.

Fundamental Units:

 3 Time Second s

## What are the fundamentals unit?

The four fundamental units are abbreviated as follows: meter, m; kilogram, kg; second, s; and ampere, A. The metric system also uses a standard set of prefixes to denote each order of magnitude greater than or lesser than the fundamental unit itself.
