MKS is an abbreviation that stands for the International System of Units (SI) base units - meter, kilogram, and second. These units are widely used in science, engineering, and everyday life to measure various physical quantities such as length, mass, time, velocity, and force.
The "M" in MKS represents the meter, which is the fundamental unit for measuring length. The meter is defined as the distance traveled by light in a vacuum during a specific fraction of a second. It is commonly used to measure distances, heights, and dimensions.
The "K" in MKS stands for kilogram, which is the unit of mass. The kilogram is defined as the mass of a platinum-iridium alloy cylinder kept at the International Bureau of Weights and Measures in France. It is frequently used to measure the mass of objects, substances, and quantities of matter.
Finally, the "S" in MKS represents the second, which is the fundamental unit of time. The second is defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between two hyperfine energy levels of the cesium-133 atom. It is used to measure time intervals, frequencies, and durations.
Together, the MKS system provides a consistent, standardized, and internationally recognized method for measuring various physical quantities precisely. It is widely adopted in scientific research, engineering calculations, and industrial applications due to its simplicity and compatibility with the SI system.
