Mass is the quantity of matter contained in a body. The mass of an object is measured in kilogram (kg).
Mass when measured in grams is a fundamental quantity. Kilograms are however 1000 grams. So kilograms is a derived unit.

Fundamental units are the units of the fundamental physical quantities in SI system. They are not formed from other units. There are a total of seven fundamental units such as meter, kilogram, ampere, and second.


Derived units are those units that are used for derived quantities. These quantities are derived from the fundamental quantities through various equations. Examples of derived units are meter per second (distance), mole per cubic meter (amount of substance concentration) and specific volume (cubic meter per kilogram). There are totally 22 SI derived units.
