1.2.1.2 System of Units

Science > Physics > Introduction to Measurements > 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. Hence it is required to define systems of units. LIST OF […]
