Fundamental unitsFundamental units, or base units, are those that cannot be decomposed into more basic units. (Note that "basic" does not mean "smaller.") Derived units, on the other hand, are those that are defined in terms of other units, which may be base units or other derived units. In the SI system, the base unit of length is the meter, the base unit of mass is the kilogram, and the base unit of time is the second. The base unit of electrical current is the ampere which is defined in terms of the force between parallel, current-carrying conductors.One of a set of unrelated units of measurement, which are arbitrarily defined and from which other units are derived. For example, in the SI system the fundamental units are the meter, kilogram, and second.
The force per unit area in SI units is Newton per meter squared (N/m^2). These units are the fundamental SI units. However, this can be simplified to Pascals.
Cell..... cell is known as the basic and fundamental unit of life...
The fundamental units are those of the SI system - The unit of Temperature, Kelvin; of Time, the second; of Mass, Kilogram; of brightness, the Candela; of physical quantity, the Mole; and of electrical current, the Ampere. With these units, all fundamental quantities may be described.Comment SI doesn't use the term, 'fundamental'. Those units listed above are termed 'base' units.
You can find the dimensions of derived units in the Wikipedia article on "Planck units".
a unit defined in terms of units of fundamental quantities
FT is a derived unit and not a fundamental unit. The fundamental unit cannot be broken down into different forms. The derived units on the other hand are made up of the fundamental units.
In FPS system of units, feet is the fundamental unit of length, one of the fundamental physical quantities.
cells are the fundamental units of living organisms.

The fundamental units of heredity are called genes.
Length is fundamental because space is fundamental and relates two other fundamental units energy and force.
In the SI, it is DEFINED as a base unit, together with the unit of length, the unit of time, and a few others. Other units are derived from these base units.
The fundamental units are based on specific standards for each unit. Derived units result from manipulating the fundamental units. For example, the SI unit for distance or length is the meter, and the SI unit for time is the second. If you divide meters by seconds, you get m/s, a derived unit for speed or velocity.
Because you have to start somewhere - you can't derive ALL units. You have to have SOME fundamental units.For example, 1 ampere = 1 coulomb / second. That also means that 1 coulomb = 1 ampere x 1 second, or that 1 second = 1 coulomb / 1 ampere. In other words, you can derive any of the three units from the other two. In practice, for base units, units were chosen that can be measured with great precision.Another AnswerThe ampere is not a 'fundamental' unit; it is a base unit. The ampere was chosen as a base unit, because it relates electrical units to mechanical units, being defined, as it is, in terms of the force (which itself is defined in terms of base units) between current-carrying conductors.You might be getting confused because, quite wrongly, the ampere is often defined as a 'coulomb per second'. While it is certainly equivalent to a coulomb per second, it is not definedin this way.
Derived units is obtained from a combination of fundamental units. Derived unit is a cubic centimeter or a cube that is a centimeter on each side.
