(CGS units) 1.0000 g/cm3 = 1000.0 kg/m3 (SI units) at 4oC temperature
1. The MKS system - and more specifically the SI is an international standard. It helps when everybody uses the same units. 2. SI uses prefixes for larger and smaller units, based on powers of 10. This makes conversion very simple. For example, to convert kilometers to meters, just multiply by 1000. With just a little practice, this can be done in your head, without pencil and paper.
SI . . . . . meter3 CGS . . . . centimeter3
mks unit for before 10 years old ,now all engineering using only SI unit only
The two most common systems of units are cgs and SI systems
CGS is NOT common nowadays. MKS is common because the SI, the international system of units, is based on it.
(MKS)or(SI)- joule CGS- erg
CGS is NOT widely used. It was in the past. The only system of measurement that is widely used today is the SI, which is a variety of MKS.
The centimetre-gram-second system (CGS) is a system of physical units. It is always the same for mechanical units, but there are several variants of electric additions. It was replaced by the MKS, or metre-kilogram-second system, which in turn was replaced by the International System of Units (SI), which has the three base units of MKS plus the ampere, mole, candela and kelvin. from Arun
The relevant SI bases are MKS.Length: cgs system uses centimetre, MKS uses metre = 100 centimetres. Mass: cgs system uses grams, MKS uses kilogram = 1000 grams. Time: they both use seconds.

(CGS units) 1.0000 g/cm3 = 1000.0 kg/m3 (SI units) at 4oC temperature
grams in the CGS measurement system, Kilograms in the Si and MKS system, or pounds in the FPS measurement system.
Actually it isn't. cgs units are sort of obsolete; nowadays, the scientific community uses SI units.

Scientists everywhere use SI units... for the most part. There are a few recidivists who have a preference for other units under certain circumstances, such as for example preferring calories to joules for thermodynamics. It's also fairly common for people to use the so-called "cgs" units instead of the modern SI "mks" units (centimeter/gram/second as opposed to meter/kilogram/second).
SI is the Systeme Internalionale of measurement in which the Metre, kilogram and Second are some primary units. An older system based on metric units used centimetre, gram, and second as the primary units. Obviously these may be converted into SI units, but the CGS system is no longer used. [Some of the definitions of the fundamental units differ between these systems.]
