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.
What are supplementary units of SI system?
the units that has not been assigned either to the fundamental units or to derived units.
When SI units combine what do they make?
Derived SI units.
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 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 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.

Derived SI units.
What measurement is the si system based on?
The SI system is based on multiples (and divisions) of ten. There are seven base units, all others are derived from these.
Why is pressure a derived quantity?
In the SI system, because that's the way it is defined. Pressure is defined as force divided by area. SI units are newton / square meter, this derived unit is called the pascal. This is the way it is defined in the SI, and in some other systems of units. You could just as well create a system of units in which pressure is a base unit, and force is derived (as the product of pressure x area). The decision, which units are base units and which units are derived, is more or less arbitrary.
What does the SI unit for speed, m/s, stand for?
The International System of Units (SI) has two type of units, base units and derived units. Speed is a derived unit. Its unit is Meter/sec. Its a scalar quantity.
How many SI units?
The SI has 7 base units. These units can be combined in an almost unlimited way to form other (derived) units. The Wikipedia article on "SI derived units" lists some examples.
Is electric current a derived unit?
It really depends on the system of units used. In the international system (SI), it is a base unit.
What is the basic unit used to measure SI?
There are seven base units in the SI system. They are; metre, kilogram, second, ampere, kelvin, mole and candela. Other units are derived from these.
Is the unit for density a derived unit or a base unit?
That will obviously depend on the system of units chosen. In the SI (International System), it is a derived unit (mass divided by volume).
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.
