Base quantities (Scalar Quantities) :
Independent quantities who have single standard units.
- time /seconds
-distance/meters
Derived Quantities (Vector Quantities):
Quantities derived by multiplying or dividing 2 base quantities.
- Velocity = distance/time
unit of Velocity = m/s

length, mass, time, eclectic current, temperature, intensity of light and amount of substance are example of base quantity. Derived quantity; the quantity that are expressed in term of base quantity are called derived quantity.

∙ 14y agoI think basic quantity or fundamental quantity are quantities that can be measured using measuring instruments. Ex. Length is measured by a ruler. Time is measured by a timewatch. Mass is measured by platform balance etc. Derived quantity are quantities that is a combination of both fundamental and derived. It uses formulas. Ex Area is square meter. Volume is cubic meter. Force is F= ma etc.

∙ 14y agoA fundamental quantity is something like length, mass or time. A derived quantity is something you get from combining fundamental measurements, like speed (comes from distance and time) or density (comes from mass and volume). The terms 'fundamental quantities' and 'derived quantaties' most likely refer to the units used, so in standard units, the fundamental quantities are the meter, kilogram, second and Ampere. There are heaps of derived quantities.

∙ 6y agoA "derived" quantity is derived from some other quantity. Since you have to start somewhere, SOME quantities must be defined first; these are the fundamental quantities, and others are derived from them. It is a more or less arbitrary decision which quantities are DEFINED as fundamental; as an example, take the standard formula for speed:distance = speed x time
If you define any two of these quantities, you can then derive the third one with this formula. It is an arbitrary decision which of these quantities are defined as fundamental - for example, some of them may be chosen as fundamental because they are easier to measure.
Here is another example: Using the fact that the area of a square is the square of the length of the side, you can define length as a fundamental quantity, and then define area as length squared; but you can just as well define area as a fundamental quantity, and then define length as the square root of an area. Since it is generally easier to measure a length, the first route is taken in many measurement systems, including the SI.

∙ 6y agoA fundamental quantity is a measurement of one of the following characteristics:
The measurement of other characteristics may be calculated on the bases of one or more of these: for example, volume = length^3, density = mass/volume and so on.
It is possible to replace some of these fundamental units by others which are "natural" units. In the above scheme, speed = distance/time, an alternative is distance = speed*time. It is, therefore, possible to use the speed of light (a natural constant) as a fundamental unit and distance as a derived unit.

Whether any quantity is a base quantity or a derived quantity depends on the definitions used in the system of measurements. In the SI, it is a derived quantity, defined as energy per unit charge. In units: joules/coulomb, where both joules and coulombs are also derived units.
Basic or fundamental quantities are seven in number. They cannot be derived right from one another. Hence they are independent. They are length, mass, time, electric current, temperature, quantity of substance, luminosity. Two sub are there. They are plane angle and solid angle. But derived are many in number. Just by the name they are derived right from the fundamental. They are area, volume, velocity, acceleration, force, momentum, magnetic induction, electric field, dipole moment, pressure, density etc etc

According to the (National Institute of Standards and Technology (NIST), "The SI is founded on seven SI base units for seven base quantities assumed to be mutually independent, as given in Table 1.""Other quantities, called derived quantities, are defined in terms of the seven base quantities via a system of quantity equations. The SI derived units for these derived quantities are obtained from these equations and the seven SI base units. Examples of such SI derived units are given in Table 2, where it should be noted that the symbol 1 for quantities of dimension 1 such as mass fraction is generally omitted. "Refer to the Related Link below in order to see Table 1 and Table 2.

It is called a base quantity.However, the distinction between a base quantity and a derived quantity is often not clear. For example, the second and metre are meant to be the base units for time and length. But the metre itself is defined in terms of the distance travelled by light, through vacuum, in 1/299,792,458 of a second. Consequently, a metre itself can be considered a derived unit.
The derived quantity is a quantity which has been derived from 2 or more base quantities. Example: Velocity is the rate of change of distance and is written in terms of distance divided by time which are two base quantities.
A base unitis a defined unit in a system of measurement that is based on an object or event in the physical world.A derived unit is a unit that is defined by a combination of base units.
Whether any quantity is a base quantity or a derived quantity depends on the definitions used in the system of measurements. In the SI, it is a derived quantity, defined as energy per unit charge. In units: joules/coulomb, where both joules and coulombs are also derived units.
Because that would lead to circular definitions.
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.
