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 do derived units look like?
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;MetreKilogramSecondAmpereKelvinMoleCandelaAll 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.
How many units are in the SI system and can i see them?
The SI has 7 base units: http://en.wikipedia.org/wiki/SI_base_unit Also, the SI has tens of derived units - perhaps hundreds of them, since you can combine the base units in many ways. Those units are ultimately derived from the 7 base units. For example, units for area, volume, speed, force, energy, pressure, electric charge, voltage, and many more, are derived from some of the base units. http://en.wikipedia.org/wiki/SI_derived_unit
How many units were derived from the seven base units of measure?
The metric, or SI, system has seven base units, from these seven all other units are derived. Length- metre (m). Time- second (s). Mass- kilogram (kg). Temperature- kelvin (K). Electric current- ampere (A). Luminous intensity- candela (cd). Amount of substance- mole (mol).
Is joule a derived unit?
Yes, the joule is a derived unit in the International System of Units (SI). It is derived from the base units of kilogram, meter, and second, and is used to measure energy, work, and heat.
Which is the functional unit of the metric system?
I have no idea what you mean with "functional unit". The SI has units to measure lots of different things; basically there are seven base units (such as the meter, the second, and the kilogram), and several dozen derived units, i.e., units derived from the base units, for example meters/second for speed.
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).
Differentiate derived units from supplementary units?
Derived units are units formed by combining base units through mathematical operations, such as area (square meters). Supplementary units are units used alongside base units to form the complete set of units in a system, such as the radian for angles in the International System of Units.
Derived units are combinations of?
base units
Mention differences between fundamental and derived units?
The fundamental units are based on specific standards for each unit. Derived units result from manipulating the fundamental units. For example, the SI unit for distance or length is the meter, and the SI unit for time is the second. If you divide meters by seconds, you get m/s, a derived unit for speed or velocity.
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.
What are combinations of base units?
Those are called derived units.
Derived units are made from combination of?
Derived units are made from a combination of base units through multiplication or division. These combinations can involve different base units raised to various powers, which allows for the creation of new units of measurement for quantities such as area, volume, velocity, and acceleration.
What is the difference between a base unit from a derived unit?
There are 7 base SI units and all other are defined using these 7 base units. See the related question below:[http://wiki.answers.com/Q/What_are_all_the_SI_unitsWhat are all SI units?]
Which best describes the term derived unit in sl?
A derived unit in the International System of Units (SI) is a unit derived from the base units through multiplication, division, or exponentiation. These derived units are obtained by combining base units with a specific mathematical formula to represent complex physical quantities.
Why are there no S.I base units for area or volume?
There are no S.I. base units for area or volume because they are derived quantities, calculated from base units. Area is derived from the square of length (meters squared), and volume is derived from the cube of length (meters cubed). The S.I. system focuses on a limited set of base units to maintain simplicity and consistency, allowing for a wide range of derived units to be expressed in relation to these fundamental measurements.
Is the unit for force a base unit or a derived unit?
The unit for force, the newton (N), is a derived unit in the International System of Units (SI). It is derived from the base units of mass, length, and time.
What is the relationship between base units and derived units?
Derived units are units built up from SI base units. It has been found that relatively few base units are required. Typical derived units are m/sec (metres per second), sometimes written m.sec-1 for speed and joules/sec, sometimes written joules.sec-1 for power. Although the latter unit is a derived unit, it has its own name, the watt, for convenience. (Nonetheless, the people who govern the business of defining units have been scrupulous in defining it in terms of base units because it's possible.) New base units are defined when phenomena are encountered which simply cannot be measured in terms of existing base units or units derived from them.
