The system used in physics - and in fact in most of science - is called the SI, which is short for International System in French.
In FPS system of units, feet is the fundamental unit of length, one of the fundamental physical quantities.
1. Length 2. Mass 3. Time 4. Temperature 5. Electric Current 6. Amount of Substance 7. Luminous intensity Comment SI doesn't use the term, 'fundamental'. Those units listed above are termed 'base' units.
Every Quantities has to be expressed which may povoke its nature. those are called units
Base quantities (Scalar Quantities) :Independent quantities who have single standard units.- time /seconds-distance/metersDerived Quantities (Vector Quantities):Quantities derived by multiplying or dividing 2 base quantities.- Velocity = distance/timeunit of Velocity = m/s
The 7 Fundamental Quantities are: length, time, mass, electric current, temperature, substance and amount of light. SI units: metre, second, kilogram, ampere, kelvin, mole, candel. Symbols of units: m, s, kg, A, K, mol, cd. Comment SI doesn't use the term, 'fundamental'. Those units listed above are termed 'base' units.
Fundamental quantities are quantities that can be measured such as mass, length and temperature. Derived quantities are quantities that has to be calculated such as pressure, volume and work done.AnswerThe SI does not define 'fundamental quantity', instead it uses the term 'Base Unit'. All other units are 'Derived Units', so-called because they are each derived from combinations of Base Units.
# Units allows use to compare quatities that are not in the same space, place or time # units also indicates the physics quantities measured or been measure as each quantities has particlar units
a unit defined in terms of units of fundamental quantities
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.
In the SI standard for physics units (see NIST website,) quantities of electricity are measured in coulombs, same as the quantity of electric charge.

Because.... There are two types of physical quantities. Fundamental and derived. Fundamental units cannot be derived from any of the two types of units while derived units can be derived from these two types of units. It's important to be clearly defined as there are so many indices of the base number. And no one can derive the units if they aren't properly defined
Standard units are used for measurements. it is taken as a fundamental unit.
