The base units of the SI system (Systeme International, as it's known in French) are kilograms (mass), meters (length/distance), and seconds (time).Because of this, the SI system is sometimes called the kg-m-s system. There are many others, but their use has become deprecated over the past 100 years or so.Believe it or not, all other SI units are based on these three units. Even seemingly unrelated units like Volts.Good luck.
kg, m, and s. They stand for kilogram, meter, and second.
From Wikipedia: "In SI units, permittivity is measured in farads per meter (F/m or A2·s4·kg−1·m−3)"
Meter, kilogram, and second. There's an argument for liters, but it is really just cubic meters.
1. Length 2. Mass 3. Time 4. Temperature 5. Electric Current 6. Amount of Substance 7. Luminous intensity Comment SI doesn't use the term, 'fundamental'. Those units listed above are termed 'base' units.
Actually, about 3 countries use non-standard measurements - the SI is the international standard.
Not only scientists use them; everybody uses most SI units - except in a few countries, such as the United States. As for the reason, it is mainly (1) for standardization. It is convenient for people all over the world to use the same units. Also, there are two other reasons: (2) Conversions are simpler. To convert 17 km to meters, just multiply by 1000 (add 3 zeroes). This can be done in your head. Now, try converting 17 miles into feet! (3) The SI units are interrelated - they form a consistent set of units. This simplifies many formulae.
The system of units scientist use to measure the properties of matter are the SI units.
You would use the cubic meter (m^3) to express the volume of a textbook in SI units.
ANSWER: It stands for Systeme Internationale
kilogram for mass, meter for length SI units commonly uses derived units for Volume such as meters cubed or liters. 1 cm^3 = 1 mL The liter is classed as a non-SI unit accepted for use with the SI. Being one thousandth of a cubic metre, the litre is not a coherent unit of measure with respect to SI.
If you mean how many countries have not officially completely changed to the SI units of measure there are 3. The United States, Liberia and Myanmar (Burma).

There are seven metric base units (m, kg, s, A, K, cd, mol). Each of these base units represents, at least in principle, different kinds of physical quantities. From these seven base units, several other units are derived. In addition to the SI units, there is also a set of non-SI units accepted for use with SI which includes some commonly used units such as the volts(that are metric but not a base unit).So volts can be also written as: m2·kg·s−3·A−1 but for easier usage V is used instead.
m^3/kg*s^2
"The" 3 basic units is wrong; the SI has SEVEN base units: kilogram, meter, second, ampere, candela, kelvin, mole.
length(meters), mass (grams), and time (seconds)This answer is incorrect. The correct answer is as follows:The SI system comprises seven BASE units and numerous DERIVED units which are all based on the seven base units. The seven base units are:length: metremass: kilogram (not gram!)time: secondelectric current: amperetemperature: kelvinluminous intensity: candelaamount of substance: mole
