MKS system

The MKS (or mks) system (or meter-kilogram-second) of units predated the current International System of Units (also known as SI), which is the current iteration of the metric system.

Although many fields, including most of the healthcare sciences have abandoned the MKS system for everyday work, there are still fields that employ them. Also, of course it is helpful to have knowledge of these legacy units when reading the older published literature.

The MKS system is a coherent system of units based on the fundamental units of meter for distance, kilogram for mass, and second for time. It was superseded by the current International System of Units.
