Derived units do not have a single 'look'. They are produced from the base units of a measuring system such as the SI system.
In the SI system there are seven base units which are;
Metre
Kilogram
Second
Ampere
Kelvin
Mole
Candela
All other units are DERIVED units.
For example the units for volume is the cubic metre and density is derived from the metre and kilogram. So density is kilograms per cubic metre in the SI system.

Why is it important to have clearly defined quantities and units in measurement?
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
When SI units combine what do they make?
Derived SI units.
How do derived units differ from base unites?
Seven metric base units make up the foundation of SI. And Specific combinations of SI base units yield derived units. That's why the differ.
What are supplementary units of SI system?
the units that has not been assigned either to the fundamental units or to derived units.
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).
Why are there 7 fundamental physical quantities and not more?
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.
Differentiate derived units from supplementary units?
suplementary units are dimendionless and are not derived from other (base) units while derived units are derived from base units and they do have dimionsions.
What derived units?
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).
The units derived from fundamental units are called?
Those are called derived units.
Derived units are made from combination of?
Derived units are made from combination of base units?
Why derived units called derived quantities?
Because they are based on - i.e. "derived from" - other units.
What are the fundamental and derived units?
In a system of units such as the SI, BASE UNITS are defined; other units are derived from those.For example, in the SI, the meter, the kilogram, and the second are base units; the units for area (meters squared), for speed and velocity (meters/second), etc. are derived from the base units. Which units are base units, and which units are derived units, really depends on how the unit is defined. For example, in the SI, pressure is a derived unit; but you can just as well invent a system in which pressure is a base unit, and some other units, that are base units in the SI, are derived in this new system.
Why are derived units more complex than fundamental units?
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.
Derived units are combinations of?
base units
What are combinations of fundamentals units?
Derived units
What are the two kinds of units?
They can be classified into fundamental units and derived units.
What units obtain by combinding Sl units are called what?
Derived units
