SI units are the International System of Units for measurements that are accepted and used worldwide in different sectors of industries. It involves units like kilogram, meter, second, kelvin, mole, ampere, candela and radian.
CGS System of Units include units centimeter, gram and second and only covers these three. This system is used in physics and chemistry related experimental fields (usually).
So, if bringing up a conclusion about superiority of either system, SI unit system wins.
2.
Dimensions are the expressions of the units of a physical quantity that usually are denoted by some specific characters. These doesn't include the value of the quantity but does include the unit and the degree of the unit.
3.
The Parallax Method is used to find out the distance between two point located or two bodies in the universe. In this, the background of the star (let) is observed and recorded from two different positions of Earth while revolving around the Sun and then compared to find the Parallax angle which further helps to find the distance of the star from the Earth.
