The International System of Units (SI) defines seven units of measure as a basic set from which all other SI units are derived. These SI base units and their physical quantities are:[1]
- metre for length
- kilogram for mass
- second for time
- ampere for electric current
- kelvin for temperature
- candela for luminous intensity
- mole for the amount of substance.
The SI base quantities form a set of mutually independent dimensions as required by dimensional analysis commonly employed in science and technology. However, in a given realization of these units they may well be interdependent, i.e. defined in terms of each other.[1]
The names of all SI units are written in lowercase characters (e.g. the metre has the symbol m), except that the symbols of units named after persons are written with an initial capital letter (e.g. the ampere has the uppercase symbol A).
Many other units, such as the litre, are formally not part of the SI, but are accepted for use with SI

Explain the difference between SI base units and derived units Give an example of each?
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.
What is the si base unit for capacity?
There is no SI base unit for capacity. In order to express capacity using SI units, you must resort to a derived unit, such as m³ or cm³ (cubic meters or cubic centimeters). In the metric system, the measurement of Liters (or Litres) may be used, but this is not an SI unit. One liter is equal to 1 dm³ (one cubic decimeter), which is a derived SI unit.
Is liter a base unit or derived unit?
In the SI the unit of volume is m3.1 m3 = 1 ooo liters (L); but the liter is also accepted as a tolerated unit of volume.CommentThe litre is not an SI unit, so it is neither a base nor a derived unit. It is a metric unit that may be used alongside SI units.
What does international system of units mean in science?
SI means 'system internationale'. It is the French acronym for the International System of Units, from which the Metric units(metres, centimetres) came from.
What is the7 basic fundamental quantities in science?
Perhaps you refer to the seven basic SI units? The number and choice of base units depends on the system used. In the case of SI, you can find the base units here: http://en.wikipedia.org/wiki/SI_base_unit
Why are si units so often in science?
SI units are more accurate than English system units
What is the difference between SI base units and derived units.?
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?]
What do you call the principal SI units that are used to derive all other SI units?
Base 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.
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.
