Thank you for your watching my video. The CGS System: It is based on three the basic units the Centimeter, the Gram and Second for the length, mass and time measurement respectively. The FPS System: It is used on the basis of the Foot, Pound and the Second for length, mass and time measure-ments respectively. The MKS System: It is based on Metre for length, the Kilogram for the mass and the Second for time. System International Units (SI): This system is globally accepted and utilizes all the seven basic units: Basic Unit of measurement- SI Unit length- metre(m) mass- Kilogram(kg) time- second(s) temperature- Kelvin(k) electric current- ampere(A) light intensity- candela(cd) amount of substance- mole(mol) Derived units of measurement: Force- Newton(n) work/energy- Joule(j) power- watt(w) pressure- Pascal(pa) frequency- Herts(Hz) Area- m^2 Volume- m^3 Density- kg/m^3 or kg/m^-3
