Hint: According to the international system of units, there are a total of seven basic quantities, and for them there are sub units defined.
Complete answer:
There are a total of 7 basic quantities as per the international system of units. The seven basic quantities are as follows,
Length: This is the quantity used to measure something in length, from one end to another. Length is basically a measure of distance. The base unit for length is meter according to the international system of units. Length is generally represented by the symbol \[l,x,r,\] etc.
Mass: Mass is the measure of the amount of matter which is there in any substance or probably in any object. The base unit for mass is kilogram according to the international system of units. Mass is generally represented by the symbol \[m\] .
Time: Time is the measure of the indefinite progress of existence and everything that occurs in daily life. The base unit for time is second according to the international system of units. Time is generally represented by the symbol \[t\] .
Electric current: Electric current is nothing but a stream of negatively charged particles called electrons through any conductor or any space. The base unit for electric current is ampere according to the international system if units. Electric current is generally represented by \[I\] or \[i\] .
Temperature: Temperature is a measure of hotness or coldness of any substance or any space. The base unit for temperature is kelvin according to the international system of units. Temperature is generally represented by \[T\] .
Amount of substance: The amount of substance is defined as the number of atomic particles the substance has in it. It is also said to be the value of the number of particles in a substance divided by Avogadro’s number. The base unit of amount of substance is mol according to the international system of units. It is generally represented by \[n\] .
Luminous intensity: It is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle. The base unit of luminous intensity is candela according to the international system of units. It is generally represented by \[{{l}_{v}}\] .
Thus, these are the seven basic quantities of the international system of units.
Note:
There are a total of seven basic quantities defined by the international system of units on which the sub units are based.
