They are:
m: meter
k: kilogram
s: second
In MKS measurement system, kilograms are used to measure mass
In the MKS (Meter-Kilogram-Second) system, the unit of displacement is the meter (m). In the CGS (Centimeter-Gram-Second) system, the unit of displacement is the centimeter (cm). In the SI (International System of Units), which is an extension of the MKS system, the unit of displacement remains the meter (m). Thus, the units of displacement across these systems are meters in MKS and SI, and centimeters in CGS.
CGS is NOT common nowadays. MKS is common because the SI, the international system of units, is based on it.
The MKS (meter-kilogram-second) system is a variant of the metric system that uses the meter for length, kilogram for mass, and second for time. The SI (International System of Units) system builds on the MKS system but includes additional base units, such as the kelvin for temperature and the candela for luminous intensity. As a result, the SI system is more comprehensive and widely used in scientific and engineering fields.
The extended form of the MKS system of measurement is called the International System of Units (SI). It includes additional units beyond the meter, kilogram, and second, such as the ampere, kelvin, mole, and candela.
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
In the MKS (Meter-Kilogram-Second) system, 12 kilometers is equivalent to 12,000 meters. This conversion is based on the fact that 1 kilometer equals 1,000 meters. Therefore, to express 12 kilometers in MKS base units, you write it as 12,000 m.
Stress has the same dimensions as pressure: force per unit area. In the SI, therefore (or in other MKS systems), the units would be newtons / meter2.
The units for acceleration in the MKS (meter-kilogram-second) system are meters per second squared (m/s^2). In the CGS (centimeter-gram-second) system, the units for acceleration are centimeters per second squared (cm/s^2).
Of or being a system of units for mechanics, using the meter, the kilogram, and the second as basic units of length, mass, and time.M - K - Seter ilogram econd
SI system is a rationalised MKS system.The earlier MKS system provided different units for different physical quantities, which was not at all convinient to use. But, the MKS system provides single unit for different physical quantities,which makes it convinient. The CGS system could not find solutions to physical quantities not involving LENGTH,TIME and MASS. Hence, it could not be used. The FPS system or BUS system was not a metric system and hence was not useful.
the mks unit is kg/m cube and the cgs unit is g/cm cube
