MKS - metre, kilogramme, second. Volume is a cube of a distance, so the MKS system uses cubic metres, but often cheats and uses litres(cubic decimetres). Density is mass divided by volume, so the MKS unit is kilos per cubic metre - but that too is seldom used.
Because it was developed in Europe for international use from the French "Systeme International" (SI)
The International system of units, From the French Systeme International d'Unites.
The full French name of SI is Systeme International d'Unites, usually abbreviated to Systeme International. The English translation of SI is the International System of Units, commonly referred to as the Metric System..
the SI units are is the newton. it stands for Systeme International, unit of force.
An expanded metric system called the International System of units.
The abbreviation for the International System of Units is SI.
It is the international system of units (systeme internationale, in French whence the initials).
SI is an abbreviation of the French "le Système International d'unités"which when translated in to English means "The International System of Units".
It stands for "Systeme Internationale d'Unites." That is French for the International System of Units.
Density is the measure of how much mass is contained in a given volume. It is calculated by dividing an object's mass by its volume. The unit for density is typically kg/m^3 in the International System of Units (SI).
Density = 0.8787 units of density measured in some units of mass and some units of volume Volume = 0.1300 units of volume Mass = Volume*Density adjusted for any conversion factor for differences in the units used for mass and volume - none of which have been specified.
The SI (Systeme International) units have made scientific calculations easier.
