If you look at the definitions of the SI units, and especially the derived units, you'll see that all the derived units are derived from other units. It might actually be possible to have even less base units, but that would make the system of units unnecessarily confusing.
What are 7 fundamental quantitieses?
The seven fundamental quantities are length, mass, time, electric current, temperature, amount of substance, and luminous intensity. These are used as base units for measuring various physical properties and quantities in the International System of Units (SI).
What are the 7 fundamental quantities of measurement?
The seven fundamental quantities used in chemistry are the quantities and units that include length in meters, time in seconds, mass in kilograms, temperature in Kelvin degrees, chemical amounts in moles, and electrical charge in coulomb. This measurements are given in meter or SI units.

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.
What are the differentiate between the basic quantities from derived quantities?
Basic quantities are quantities which can be arrived at without performing any mathematical procedure. Derived quantities are those which can be arrived at only after performing mathematical procedure.

What is a derived unit?
derived units come from basic units such as length, time, electrical current.AnswerIn SI, Derived Units are any units that are not Base Units. There are seven Base Units, from which all Derived Units are formed. For example, a coulomb (derived unit) is equal to an ampere second (both Base Units).
