a specific combination of base units with its own name
Most scientists use the SI, or international standard, system. This includes units and prefixes. The units can be expanded into base (or original) and derived (made from the base) units. The prefixes include centi- (.01), milli- (.001), kilo (1000), and many others. The base units include meters (length or distance), kilograms (mass), and seconds (time), while derived units include liters (Volume), meters per second (speed), and meters per square seconds(accelleration)
The SI is founded on seven SI base units for seven base quantities assumed to be mutually independent.These are :length meter m mass kilogram kg time second s electric current ampere A thermodynamic temperature kelvin K amount of substance mole mol luminous intensity candela cdOther quantities, called derived quantities, are defined in terms of the seven base quantities via a system of quantity equations. The SI derived units for these derived quantities are obtained from these quations and the seven SI base 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?]
The metric system uses differing prefixes to show multiples of ten for base units. To indicate one thousand units, the prefix kilo- is used, as in kilometer, or kilowatt.
Prefixes are useful when describing SI units because they allow for easy conversion between different units of measurement by indicating a multiple or fraction of the base unit. This helps to express quantities in a more manageable and standardized way.
no; however, femto- is an SI prefix meaning 10-15
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?]
The principal SI units used to derive all other SI units are the base SI units. These are the units for physical quantities such as length, time, mass, electric current, temperature, amount of substance, and luminous intensity.
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.
For units larger or smaller than the base units, you can use prefixes such as kilo (x 1000), Mega (x 1 million), milli (x 0.001), micro (x 0.000 001), etc.; for a complete list, search the Wikipedia for "SI prefixes".

A Joule in SI base units is: 1 kg · m2/s2
SI is a base 10 standardized system
The base unit for volume is the cubic metre, because the units are cubed, the normal prefixes are a little confusing, so the non-SI unit litre is used for most everyday volumes. one cubic metre is 1000 litres.AnswerThere is no SI base unit for volume. Its unit is the cubic metre (m3), which is a derived unit.There are seven base units in SI, these being:metre (length)kilogram (mass)second (time)ampere (current)kelvin (temperature)candela (luminous intensity)mole (amount of substance)
A Joule in SI base units is: 1 kg · m2/s2
