👉 The concept of combining units in the CGS system (Centimeter, Giga-Centimeter, Square Meter) is a fundamental unit system used in physics. The CCGS system includes the following units: 1. Centimeters (cm): 1 cm = 0.01 m. 2. Gigacentimeters (g/cm^3): 1 g/cm^3 = 10^-6 m^3/kg. 3. Square meters (m^2):
